AFAIK, redefining standard macros when the corresponding header
(here <limits.h>) has been including is not allowed by the C standard.
So, problems might appear...

I think the real fix would be not to reuse the standard macro names.
For instance, GMP could define GMP_INTMAX and so on for its own use.

Ah, OK, I didn't see this.
