cpp oddity causes bootstrap error

[Robert Lipe]

My targets fail to bootstrap becuaes they're trying to include files
that don't exist.  While picking apart the build, it looks like includes
that are meant to be conditionally reached are unconditionally reached.

$ cat x.c
#if 0 
#include <machine/ansi.h>
#endif    
(robertl) rjlhome:/play/negcs/gcc
$ ./xgcc  -E -B./ x.c
x.c:2:25: machine/ansi.h: No such file or directory
# 1 "x.c"

Zack, is this just temporary breakage in the new preprocessor?

Thanx,
RJL
