Re: [MIT-Scheme-devel] compiling for OS X

I've attached the transcript.  The build fails here in "microcode/confshared.h":

  #ifndef PC_ZERO_BITS
  #  ifdef CC_IS_NATIVE
  #    include "Error: confshared.h: Unknown PC alignment."
  #  else
  #    define PC_ZERO_BITS 0
  #  endif
  #endif

My guess is that the problem is that <__IA32__> isn't defined, and
therefore <PC_ZERO_BITS> is never defined.  But when I define it, I
eventually get lots of errors like this:

  cmpaux-i386.s:188:32-bit absolute addressing is not supported for x86-64

There must be some way to force a 32-bit compile at the GCC level.
Doesn't it look like that's what's needed?

The binary built on 10.5.8 works fine on Snow Leopard.
