the preprocessed file, and it doesn't happen at -O0.

Version-Release number of selected component (if applicable):
gcc-3.1-0.18

How Reproducible:
100%

Steps to Reproduce:
1. Grab Omni-0.5.1-1.src.rpm.
2. rpm -bp Omni.spec
3. c++ -fPIC -O1 -I/usr/include/glib-1.2 -I/usr/lib/glib/include -c 
OmniIJSProxy.cpp
