This sounds like a bug in cpp. I can't find the relevant change in the 
GCC 4.4.2 changelog:
    http://gcc.gnu.org/gcc-4.4/changes.html

This seems to be new and undocumented behaviour which has affected other 
software projects:

Which files were specifically affected by this change?

If you tell the invocation of CPP affected to use the '-P' option, does 
this resolve the issue?
