So, it won't build on 32-bit Mac OS... but not for any sane reason; rather, it won't build because it's failing to pick up the appropriate gnulib shims to make the 'environ' function visible.  I mean, HOW?  It works just fine on 64-bit!  Is this something that the ./configure script does differently between the two?

Just in case, is it correctly defined?
It should be this for Apple:

```
#include <crt_externs.h>
#define environ (*_NSGetEnviron())
```
I.e. different from Linux one.
