PATCH: Check LONG_MAX > INT_MAX for __WORDSIZE

I certainly agree with Paul that this is far cleaner, even if the
limits.h trick were technically acceptable (which it's not, for the
reasons Paul gave).  I was going to ask if there were really x86_64
systems with GCC < 3.3 where libc actually works.  But if you make x32
compilers predefine __ILP32__ and test that then we don't need to figure
out the answer.

I think it would be best to be consistent in the sense of the tests we
use.  So once you've changed the compiler, please make all the tests in
libc be on __ILP32__ rather than !__LP64__.


Thanks,
Roland
