Is this script really needed?  Are there any other cases of programs
checking for i386 via cpp?  If imake is the only one, why go thru the
trouble of the script for one specific case?

Wouldn't it be much easier to edit xmkmf and add -Di386 to the args list?

Also, I'm not sure if it's been mentioned, but when XFree86 is recompiled
with egcs, the problem goes away as imake defines -Di386 itself.
