The GCC preprocessed files to go with the simple, one-source-file test case.

And here are the gcc preprocessed files that go with the more simple test case.
The gcc -v info from the machine used to produce these is as follows:

Please note, however, that I've been able to reproduce this bug on a new Fedora
10 installation as well... that install's gcc-v is as follows:
