[CWEB] New release 4.3.
This release introduces new features to CWEB 4: * Former option '-t' is now called '-c'. - New option '-t' for CWEAVE when dealing with 'typename' in C++ templates. - New option '-k' for CTANGLE to keep '-separators in numeric literals. * Support for "variadic macros" along "variadic functions". * @d is printed similar to #define (and vice versa): - '#' is no longer printed in boldface. - Spacing is similar in most cases. * Support for extended C99/C++ numeric literals: - hexadecimal, octal, and -- new! -- binary numbers. - NOTE: 'cwebmac.tex 4.3' is NOT compatible with CWEAVE 4.2 and older and vice versa. * Long parameter lists in ANSI function definitions are indented similar to old-style function parameters. - Option '-i' works similar for old-style and modern function headers. * Additional C99/C++ keywords -- from 'alignas' to 'thread_local' -- are supported internally. * '@i'nclude file 'iso_types.w' for numeric types (in addition to 'c++lib.w'). * Countless code modifications, including some corrections amd improvements. Thanks and cudos to Github user "@texdraft" for numerous contributions to this feature release! git-svn-id: svn://tug.org/texlive/trunk@58884 c570f23f-e606-0410-a88d-b1316a301751
