Re: test for preprocessor fails on iPhoneOS

[Paul Eggert]

It looks like the user can't compile a file like this:

#include <limits.h>
int big = INT_MAX;

because the compiler in the user's environment will say "error: 
Unsupported architecture".  If so, this sounds like it's a configuration 
problem on the user's side, as C code like that should work regardless 
of whether Autoconf is being used.
