+       maintainer-makefile: make syntax-check a no-op from tarballs
+       * top/maint.mk (no-vc-detected): New rule.
+       (local-checks-available): Use it to avoid hanging if someone tries
+       'make syntax-check' from a tarball.  Also append to any non-syntax
+       checks already defined in cfg.mk.

+       longlong: tune, particularly for common case of c99
+
+       * m4/longlong.m4 (AC_TYPE_LONG_LONG_INT): Don't bother compiling
+       or running anything if c99, or if unsigned long long int does not
+       work.  In either case, we know the answer without further tests.
+       Do not compile _AC_TYPE_LONG_LONG_SNIPPET twice.  Instead, compile
+       it at most once, and use its results for both long long int and
+       unsigned long long int.  This is more likely to be efficient in
+       the common case where the program wants to check for both long
+       long int and unsigned long long int.
+       (AC_TYPE_UNSIGNED_LONG_LONG_INT): Don't bother compiling if c99,
+       since the answer is already known.
