Forcing 32 bit mode in configure

[Mike Hearn]

Hi,

Does anybody know how to force gcc to compile in 32 bit mode on 64 bit
chips, and if so could they please write a patch? I've seen quite a few
posts to end user forums lately saying that people were trying to compile
Wine on AMD64 (and failing, obviously).

thanks -mike

Wouldn't passing -m32 (if I recall correctly) to gcc tell it to produce
32 bit code?

I seem to recall that at least on the later Debian's the compiler is 
bi-arch and you can tell it what kind of code to generate.  There was a 
howto somewhere about how to compile a 64-bit Linux kernel on AMD64, and 
I also seem to recall -m32, but that only really influences the size of 
ints, longs and pointers, which I believe is the real issue here.

I can try.

It would be nice to have a configure option or something for 32 vs
64bit mode. I have been playing around with a native port to AMD64 on
sourceforges compile farm and have quite a few patches for the headers
and other stuff I was planing on cleaning up and submitting.

Thanks
Steven
