Well, it seems this compiler does not grok long long numbers in preprocessor
expressions. But this is an ISO C 99 requirement, and test-stdint checks for it.

Do you have any suggestion? Writing the constants with a single L will not
work, since sizeof (long) < sizeof (long long) on these 32-bit machines.
Pretending that the compiler does not support 'long long' in the autoconf tests
would make some code (in human.c and others) work worse than it currently does.
