Here is a test-case that might be easier (certainly faster)
than bootsrapping with --enable-intermodule.

Just do:
cc1 Csrc1.c Csrc2.c -o Ctest.s
gcc -o Ctest Ctest.s
./Ctest

This should work.  It doesn't with the current head, at least with my
(un-checked-in) patch.  (It is possible the fault is my patch, but I
think Zack's patch is more likely to blame.)

If it doesn't work, running gdb on cc1 should be relatively easy.
