+
+ stdint: respect system's intmax_t if INTMAX_MAX
+ * lib/stdint.in.h (intmax_t, uintmax_t): If the system defines
+ INTMAX_MAX, assume its intmax_t is OK. Similarly for and
+ uintmax_t. This is for some Mac OS X builds, where intmax_t is
+ long but int64_t is long long, and where we will clash with the
+ system intmax_t if we override it. See
+ <http://lists.gnu.org/archive/html/bug-gnulib/2011-07/msg00160.html>.
+ (INTMAX_C, UINTMAX_C): For consistency, respect the system's
+ INTMAX_C if INTMAX_MAX and INTMAX_C are both defined, and
+ similarly for UINTMAX_C.
