Please try wrapping the problem prototype in #ifdef RTX_CODE, like some 
other prototypes in that header.  (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.)
