+ for kpsewhich.
+
+ * pathsearch.c (KPSE_CASEFOLDING_SEARCH): new compile-time macro
+ to support case-insensitive searches on case-sensitive operating
+ systems, that is, not Windows. Most other changes here are
+ conditional on it.
+
+ (print_space_list): helper fn for debugging output.
+ (readable_file_fn_type): new typedef for casefold_readable_file
+ and kpathsea_readable_file.
+ (casefold_readable_file): new fn to check for a file ignoring case.
+ (dir_list_search),
+ (dir_list_search_list): take an additional function pointer argument
+ and call it, instead of only kpathsea_readable_file. Return
+ the matched name instead of the original name. (This would have
+ caused failure before with the ENAMETOOLONG kludge; guess that
+ never actually happens.)

+5.4 Casefolding search
+======================
+
+In Kpathsea version 6.3.0 (released with TeX Live 2018), a new fallback
+search was implemented on Unix-like systems, including Macs: for each
+path element in turn, if no match is found by the normal search, and the
+path element allows for checking the filesystem, a second check is made
+for a case-insensitive match.
+
+ This is enabled at compile-time on Unix systems, and enabled at
+runtime by setting the configuration variable 'texmf_casefold_search',
+to a true value, e.g., '1'; this is done by default in TeX Live.
+
+* Menu:
+
+* Rationale: Casefolding rationale.
+* Examples: Casefolding examples.
+
+
+File: kpathsea.info, Node: Casefolding rationale, Next: Casefolding examples, Up: Casefolding search
+
+5.4.1 Casefolding rationale
+---------------------------
+
+The purpose of the fallback casefolding search is to ease moving complex
+documents between case-insensitive (file)systems and case-sensitive
+ones. In particular, Apple decided to make the default filesystem on
+Macs be case-insensitive some years ago, and this has exacerbated a
+problem of people creating documents that use, say, an image under the
+name 'foo.jpg', while the actual file is named 'foo.JPG' or 'Foo.jpg'.
+It works on the Mac but if the document is transferred and run on a
+standard case-sensitive Unix (file)system, the file can't be found, due
+only to differences in case.
+
+ This same problematic scenario has always existed on Windows, but for
+whatever reason, it has become much more common since Apple also went to
+a case-insensitive filesystem. Hence the move to change the Kpathsea
+behavior now.
+
+ The fallback case-insensitive search is omitted at compile-time on
+Windows, where (for practical purposes) all file names are
+case-insensitive at the kernel level, and so the normal search will
+already have definitively matched or not. Therefore, search results in
+unusual cases can be different on Windows and Unix--but this has always
+been true.
+
+
+File: kpathsea.info, Node: Casefolding examples, Prev: Casefolding rationale, Up: Casefolding search
+
+5.4.2 Casefolding examples
+--------------------------
+
+The casefolding implementation prefers exact matches to casefolded
+matches within a given path element, so as to retain most compatibility.
+Backward compatibility is not perfect, however, as a casefolded match
+may be found in an earlier path element than an exact match was
+previously found (see example #4 below). Still, preferring the match in
+the earlier element seemed potentially less confusing than otherwise,
+and is in fact consistent with past behavior on Windows. Since case
+mismatches are rare to begin with, and name collisions with respect only
+to case thus even more rare, the hope is that it will not cause
+difficulties in practice.
+
+ If it's desirable in a given situation to have the exact same search
+behavior as previously, that can be accomplished by setting the
+configuration variable 'texmf_casefold_search' to '0' (*note Path
+sources::).
+
+ Some examples to illustrate the new behavior follow.
+
+ Example #1: suppose the file './foobar.tex' exists. Now, searching
+for './FooBar.TeX' (or any other case variation) will succeed, returning
+'./foobar.tex'--the name as stored on disk. In previous releases, or if
+'texmf_casefold_search' is false, the search would fail.
+
+ Example #2: suppose we are using a case-sensitive (file)system, and
+the search path is '.:/somedir', and the files './foobar.tex' and
+'/somedir/FooBar.TeX' both exist. Both now and previously, searching
+for 'foobar.tex' returns './foobar.tex'. However, searching for
+'FooBar.TeX' now returns './foobar.tex' instead of
+'/somedir/FooBar.TeX'; this is the incompatibility mentioned above.
+Also (as expected), searching for 'FOOBAR.TEX' (or whatever variation)
+will now return './foobar.tex', whereas before it would fail. Searching
+for all ('kpsewhich --all') 'foobar.tex' will return both matches.
+
+ Example #3: same as example #2, but on a case-insensitive
+(file)system: both now and previously, searching for 'FooBar.TeX'
+returns './foobar.tex', since the system considers that a match. The
+Kpathsea casefolding never comes into play.
+
+ Example #4: if we have (on a case-sensitive system) both
+'./foobar.tex' and './FOOBAR.TEX', searching with the exact case returns
+that exact match, now and previously. Searching for 'FooBar.tex' will
+now return one or the other (chosen arbitrarily), rather than failing.
+Perhaps unexpectedly, searching for all 'foobar.tex' or 'FooBar.tex'
+will also return only one or the other, not both (see more below).
+
+ Example #5: the font file 'STIX-Regular.otf' is included in TeX Live
+in the system directory 'texmf-dist/fonts/opentype/public/stix'.
+Because Kpathsea never searches the disk in the big system directory,
+the casefolding is not done, and a search for 'stix-regular.otf' will
+fail (on case-sensitive systems), as it always has.
+
+ The caveat about not searching the disk amounts to saying that
+casefolding does not happen in the trees specified with '!!' (*note
+ls-R::), that is, where only database ('ls-R') searching is done. In
+TeX Live, that is the 'texmf-local' and 'texmf-dist' trees (also
+'$TEXMFSYSCONFIG' and '$TEXMFSYSVAR', but those are rarely noticed).
+The rationale for this is that in practice, case mangling happens with
+user-created files, not with packages distributed as part of the TeX
+system.
+
+ One more caveat: the purpose of 'kpsewhich' is to exercise the path
+searching in Kpathsea as it is actually done. Therefore, as shown
+above, 'kpsewhich --all' will not return all matches regardless of case
+within a given path element. If you want to find all matches in all
+directories, 'find' is the best tool, although the setup takes a couple
+steps:
+
+ kpsewhich -show-path=tex >/tmp/texpath # search path specification
+ kpsewhich -expand-path="`cat /tmp/texpath`" >/tmp/texdirs # all dirs
+ tr ':' '\n' </tmp/texdirs >/tmp/texdirlist # colons to newlines
+ find `cat /tmp/texdirlist` -iname somefile.tex -print </tmp/texdirlist
+
+ Sorry that it's annoyingly lengthy, but implementing this inside
+Kpathsea would be a lot of error-prone trouble for something that is
+only useful for debugging. If your 'find' does not support '-iname',
+you can get GNU Find from <https://www.gnu.org/software/findutils>.
+
+ The casefolding search is implemented in the source file
+'kpathsea/pathsearch.c'. Two implementation points:
+
+ * Kpathsea never tries to check if a given directory resides on a
+ case-insensitive filesystem, because there is no efficient and
+ portable way to do so. All it does is try to see if a potential
+ file name is a readable normal file (with, usually, the 'access'
+ system call).
+
+ * Kpathsea does not do any case-insensitive matching of the
+ directories along the path. It's not going to find
+ '/Some/Random/file.tex' when looking for '/some/random/file.tex'.
+ The casefolding only happens with the elements of the leaf
+ directory.

+@cindex casefolding fallback rationale
+@cindex rationale for casefolding fallback
+@cindex system-dependent casefolding behavior
+
+@cindex filesystem, case-(in)sensitive
+@cindex Apple filesystem, case-insensitive
+@cindex Mac filesystem, case-insensitive
+The purpose of the fallback casefolding search is to ease moving
+complex documents between case-insensitive (file)systems and
+case-sensitive ones. In particular, Apple decided to make the default
+filesystem on Macs be case-insensitive some years ago, and this has
+exacerbated a problem of people creating documents that use, say, an
+image under the name @file{foo.jpg}, while the actual file is named
+@file{foo.JPG} or @file{Foo.jpg}. It works on the Mac but if the
+document is transferred and run on a standard case-sensitive Unix
+(file)system, the file can't be found, due only to differences in
+case.
+
+This same problematic scenario has always existed on Windows, but for
+whatever reason, it has become much more common since Apple also went
+to a case-insensitive filesystem. Hence the move to change the
+Kpathsea behavior now.
+
+@cindex Windows and casefolding
+The fallback case-insensitive search is omitted at compile-time on
+Windows, where (for practical purposes) all file names are
+case-insensitive at the kernel level, and so the normal search will
+already have definitively matched or not. Therefore, search results
+in unusual cases can be different on Windows and Unix---but this has
+always been true.
+
+
+@node Casefolding examples
+@subsection Casefolding examples
+
+@cindex casefolding examples
+@cindex examples, of casefolding searches
+
+The casefolding implementation prefers exact matches to casefolded
+matches within a given path element, so as to retain most
+compatibility. Backward compatibility is not perfect, however, as a
+casefolded match may be found in an earlier path element than an exact
+match was previously found (see example #4 below). Still, preferring
+the match in the earlier element seemed potentially less confusing
+than otherwise, and is in fact consistent with past behavior on
+Windows. Since case mismatches are rare to begin with, and name
+collisions with respect only to case thus even more rare, the hope is
+that it will not cause difficulties in practice.
+
+If it's desirable in a given situation to have the exact same search
+behavior as previously, that can be accomplished by setting the
+configuration variable @code{texmf_casefold_search} to @samp{0}
+(@pxref{Path sources}).
+
+Some examples to illustrate the new behavior follow.
+
+Example #1: suppose the file @file{./foobar.tex} exists. Now,
+searching for @file{./FooBar.TeX} (or any other case variation) will
+succeed, returning @file{./foobar.tex}---the name as stored on disk.
+In previous releases, or if @code{texmf_casefold_search} is false, the
+search would fail.
+
+Example #2: suppose we are using a case-sensitive (file)system, and
+the search path is @samp{.:/somedir}, and the files
+@file{./foobar.tex} and @file{/somedir/FooBar.TeX} both exist. Both
+now and previously, searching for @file{foobar.tex} returns
+@file{./foobar.tex}. However, searching for @file{FooBar.TeX} now
+returns @file{./foobar.tex} instead of @file{/somedir/FooBar.TeX};
+this is the incompatibility mentioned above. Also (as expected),
+searching for @file{FOOBAR.TEX} (or whatever variation) will now
+return @file{./foobar.tex}, whereas before it would fail. Searching
+for all (@samp{kpsewhich --all}) @file{foobar.tex} will return both
+matches.
+
+Example #3: same as example #2, but on a case-insensitive
+(file)system: both now and previously, searching for @file{FooBar.TeX}
+returns @file{./foobar.tex}, since the system considers that a match.
+The Kpathsea casefolding never comes into play.
+
+Example #4: if we have (on a case-sensitive system) both
+@file{./foobar.tex} and @file{./FOOBAR.TEX}, searching with the exact
+case returns that exact match, now and previously. Searching for
+@file{FooBar.tex} will now return one or the other (chosen
+arbitrarily), rather than failing. Perhaps unexpectedly, searching
+for all @file{foobar.tex} or @file{FooBar.tex} will also return only
+one or the other, not both (see more below).
+
+Example #5: the font file @file{STIX-Regular.otf} is included in
+@TeX{} Live in the system directory
+@file{texmf-dist/fonts/opentype/public/stix}. Because Kpathsea never
+searches the disk in the big system directory, the casefolding is not
+done, and a search for @samp{stix-regular.otf} will fail (on
+case-sensitive systems), as it always has.
+
+The caveat about not searching the disk amounts to saying that
+casefolding does not happen in the trees specified with @samp{!!}
+(@pxref{ls-R}), that is, where only database (@file{ls-R}) searching
+is done. In @TeX{} Live, that is the @samp{texmf-local} and
+@samp{texmf-dist} trees (also @code{$TEXMFSYSCONFIG} and
+@code{$TEXMFSYSVAR}, but those are rarely noticed). The rationale for
+this is that in practice, case mangling happens with user-created
+files, not with packages distributed as part of the @TeX{} system.
+
+One more caveat: the purpose of @code{kpsewhich} is to exercise the
+path searching in Kpathsea as it is actually done. Therefore, as
+shown above, @samp{kpsewhich --all} will not return all matches
+regardless of case within a given path element. If you want to find
+all matches in all directories, @code{find} is the best tool, although
+the setup takes a couple steps:
+
+@example
+kpsewhich -show-path=tex >/tmp/texpath # search path specification
+kpsewhich -expand-path="`cat /tmp/texpath`" >/tmp/texdirs # all dirs
+tr ':' '\n' </tmp/texdirs >/tmp/texdirlist # colons to newlines
+find `cat /tmp/texdirlist` -iname somefile.tex -print </tmp/texdirlist
+@end example
+
+@cindex Findutils, GNU package
+@opindex -iname@r{, find predicate}
+Sorry that it's annoyingly lengthy, but implementing this inside
+Kpathsea would be a lot of error-prone trouble for something that is
+only useful for debugging. If your @code{find} does not support
+@code{-iname}, you can get GNU Find from
+@url{https://www.gnu.org/software/findutils}.
+
+The casefolding search is implemented in the source file
+@file{kpathsea/pathsearch.c}. Two implementation points:
+
+@itemize
+@findex access @r{system call}
+@item
+Kpathsea never tries to check if a given directory resides on a
+case-insensitive filesystem, because there is no efficient and
+portable way to do so. All it does is try to see if a potential file
+name is a readable normal file (with, usually, the @code{access}
+system call).
+
+@item
+Kpathsea does not do any case-insensitive matching of the directories
+along the path. It's not going to find @file{/Some/Random/file.tex}
+when looking for @file{/some/random/file.tex}. The casefolding only
+happens with the elements of the leaf directory.
