Extended Description

The llvm-gcc3 frontend (based on GCC 3.4 sources) does not correctly determine
the source filename for C constructs under certain conditions. This leads to
two errors:

1. Warning and error messages alert the user to look at the wrong file.
2. LLVM debugging instructions contain the wrong filename.

Re-assign bug to myself as I believe I have a fix for it.

Source file for test
The bug can be reproduced with the following command line (once all files are
uploaded):
llvm-gcc -g -S test.c

The error message for the line containing fluffy will claim to originate from
test1.h and not test.c.
