Somehow I never noticed this until making what seemed like a pointless GCC config.

You can apparently build a GCC like this:

sh configure –host=i386-winnt35 –target=alpha-winnt35

And you can get a cross compiler.

The real question is, does it work?  I don’t know I don’t have a cross assembler, linker or a target machine.

This is what the output looks like, which looks nothing like targeting the i386 so I guess so?
