Based on the results from [1] I guess the preprocessor looks for the sign in bit 31 instead of in bit 63. > I considered working around the problem by causing 32-bit Solaris > builds to fall back into a 32-bit-only world.

Indeed: While 32-bit-only mode is OK for GNU gettext, it is not sufficient for tar or gzip... > In the meantime, code should not expect > #if to work with literals wider than 32 bits. */ Can you document this limitation in doc/headers/stdint.texi please? Possibly also in autoconf.texi section "Portable C and C++ Programming"? Bruno [1] http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html
