Unfortunately, but 8603 seems to cause internal compiler errors on select files
when using -O3. -O{s,0,1,2} are unaffected.

I'm attaching pp.i (preprocessed pp.c from libperl), and flist.i (preprocessed
flist.c from rsync) as test cases.

gcc-4.3.4 does not exhibit this failure, but when patched from bug 8603, it
fails. gcc-4.4.1 does not exhibit this failure, but gcc-4.4.2, which includes
the patch from 8603, does fail.
