INT_MAX definition in gmp-impl.h conflicts with limits.h

[Marc Glisse]

Hello,

I was compiling gmp with clang (no issue except for the use of jb,pt in 
mpn/x86_64/mod_34lsub1.asm), and then I ran the testsuite and hit this 
issue: on linux, limits.h includes bits/xopen_lim.h which contains this 
code:

#ifdef INT_MAX
# if INT_MAX == 32767
#  define WORD_BIT      16
...

On the other hand, gmp-impl.h defines INT_MAX as something not 
preprocessor-friendly (with casts). The combination doesn't work. I can 
work around it by including tests.h before gmp-impl.h in the C++ test 
files, but that doesn't feel right.

Any opinion on the best way to go about this?
