Using -imacros causes cc1 to segfault.  Sorry there isn't a patch associated
with this - I'm behind on some other stuff and don't have time.  If noone looks
at this in the next couple of weeks, I'll do it then.  I'm using CVS from
November 03, 2003.

Here's my testcase:

$ cat a.h
#define IOO_IMPORTS import "priv.h";

$ cat a.c
#ifdef IO_IMPORTS
IO_IMPORTS
#endif

$ build.gcc/gcc/cc1 -E -imacros a.h a.c
# 1 "<built-in>"
# 1 "<command line>"
# 1 "./a.h" 1
# 2 "<command line>" 2
# 1 "a.c"
a.c:0: internal compiler error: Segmentation fault
