[PATCH] MiG: handle '-isystem ...' correctly

[Thomas Schwinge]

Hello!

MiG currently breaks when '-isystem ...' is specified on its command
line:
#v+
echo '#include <mach/mach.defs>' | CC='gcc' CPP='gcc -E -x c' mig - /dev/null 
-DMACH_IPC_COMPAT=0 -DSTANDALONE -DTypeCheck=0 -I../include -I.

#v-

Note that there are still a huge number of other options left to make MiG
break, but caring for all of them would nearly mean reimplementing GCC's
frontend 'gcc'--I'd suggest to just add those causing real problems, like
the one above.


Could someone please apply the attached mig_-isystem.patch?
