+Shared cache: cleanup and various improvements / corrections.
+  * acinclude.m4:
+      - test $enable_shared_cache instead of $mpfr_want_shared_cache;
+      - check ISO C11 thread support and/or POSIX thread support
+        only when necessary;
+      - when checking support for POSIX threads (pthread), also check
+        that pthread_rwlock_t is supported, as it is needed by MPFR
+        and conditionally defined in glibc's bits/pthreadtypes.h (via
+        <pthread.h>);
+      - with POSIX threads, also set CC="$PTHREAD_CC" as documented by
+        ax_pthread (autoconf-archive). This is not guaranteed to work,
+        but according to the ax_pthread.m4 source, in the cases where
+        "$PTHREAD_CC" != "$CC", not setting it will probably not work
+        either;
+      - handle --enable-shared-cache early in MPFR_CONFIGS, because
+        the use of POSIX threads (pthread) may need to change CC,
+        CFLAGS, and LIBS (thus affecting other tests);
+      - removed the now useless MPFR_CHECK_SHARED_CACHE function.
+  * configure.ac: no longer set the mpfr_want_shared_cache variable,
+    as enable_shared_cache (now used) already has the same usage.
+  * acinclude.m4, configure.ac: moved the compatibility test of the
+    configure options even earlier, from acinclude.m4 to configure.ac,
+    just after the code that defines them. Also added an associated
+    AC_MSG_CHECKING message for better clarity.
+  * src/mpfr-impl.h: added a comment about the cache-related types,
+    which depend on the locking methods.
+  * src/mpfr-thread.h: fixed the lock macros:
+      - in case of failure, one must abort, otherwise this would
+        generally be undefined behavior;
+      - added missing "do {} while (0)" (currently not mandatory).
+  * tests/tversion.c: update concerning the shared cache, to be
+    consistent with the other mpfr_buildopt_*_p features:
+      - check that mpfr_buildopt_sharedcache_p() and
+        MPFR_WANT_SHARED_CACHE match;
+      - for the output of the value, test mpfr_buildopt_sharedcache_p()
+        instead of the macro.
+  * NEWS: update.

+[src/strtofr.c] Fixed various issues. In particular, the error analysis
+  with associated code was incorrect (due to the bad correction r8384
+  of a past bug, later really fixed in r11056). Also adapted the code
+  to work with small-size limbs.
+[tests/tstrtofr.c] Added tests, including random tests. In particular,
+  some part of the code was tested only on hard-to-round cases, meaning
+  that some potential issues could not be detected (intermediate results
+  were thrown out due to the next Ziv iteration). Moreover, in case of
+  failure of some particular test, output the probable cause of this
+  failure (GCC bug 86554) with a workaround.
+(merged changesets associated with these files r12566-13306,13364-13365
+from the trunk)
+Note: There may still remain issues with mpfr_strtofr, to be checked
+later. At least, the tests do not fail.

+Changed paths:

+
+[src/vasprintf.c] Fixed several bugs in buffer_sandwich, which could
+yield memory corruption with non-default memory allocators and other
+undefined behavior; check the return value when this function is called.
+
+Details:
+  * check integer overflow on the size computations;
+  * computation of q and r without tests;
+  * fixed the case where r > len (e.g. len = 1 and tz = 1);
+  * in the loop, increase the str pointer only when needed, otherwise
+    str could be beyond of the end of the string of the digits, which
+    is undefined behavior.
+
+The first consequence of the r > len issue was an incorrect generated
+string. Moreover, since the generated string was shorter than expected,
+mpfr_free_str would provide an incorrect buffer size to the "free"
+function of the current GMP memory allocator. By default, this size is
+ignored, but it may matter if the memory allocators have been changed
+with the mp_set_memory_functions GMP function, in which case a possible
+consequence could be memory corruption.
+
+Note: This corresponds to r12869 from the trunk. Other changes in the
+trunk (dead code removal...) have not been applied.

          We must have base^(pstr_size-1) >= (2^(GMP_NUMB_BITS))^ysize
          (in the worst case, the first digit is one and all others are zero).
          i.e., pstr_size >= 1 + ysize*GMP_NUMB_BITS/log2(base)
           Since ysize ~ prec/GMP_NUMB_BITS and prec < Umax/2 =>
           ysize*GMP_NUMB_BITS can not overflow.
          We compute pstr_size = 1 + ceil(ysize_bits * Num / Den)
-          where Num/Den >= 1/log2(base)
-         It is not exactly ceil(1/log2(base)) but could be one more (base 2)
+          where 1/log2(base) <= Num/Den <= 1
+         It is not exactly ceil(1/log2(base)) but could be one more (base 2).
          Quite ugly since it tries to avoid overflow:
          let Num = RedInvLog2Table[pstr->base-2][0]
          and Den = RedInvLog2Table[pstr->base-2][1],
          and ysize_bits = a*Den+b,
          then ysize_bits * Num/Den = a*Num + (b * Num)/Den,
          thus ceil(ysize_bits * Num/Den) = a*Num + floor(b * Num + Den - 1)/Den
+
+         Note: denoting m = pstr_size and n = ysize_bits, assuming we have
+         m = 1 + ceil(n/log2(b)), i.e., b^(m-1) >= 2^n > b^(m-2), then
+         b^(m-1)/2^n < b, and since we consider m characters of the input,
+         the corresponding part is less than b^m < b^2*2^n.
+         This implies that if b^2 < 2^GMP_NUMB_BITS, which for b <= 62 holds
+         for GMP_NUMB_BITS >= 12, we have real_ysize <= ysize+1 below
+         (this also implies that for GMP_NUMB_BITS >= 13, the number of bits
+         of y[real_ysize-1] below is less than GMP_NUMB_BITS, thus
+         count < GMP_NUMB_BITS).

+                    hide mistakes since one may have 1/2 <= z < 1 < b^e.
+

+             * if the quotient has one extra bit, then 1 <= |y/z| < 2
