(Including machmode.h in i386-common.c might cause other problems, and certainly would be against modularity. Ideally tm.h and tm_p.h would be split into common parts and parts used only in the compiler proper, but that's a long way off.)

I have bootstrapped revision 175077 with the patch in comment #2.
This pr has been fixed by revision 175110. Closing.
