Yes, this is apparently due to cpp mistaking the comments at the top of 
the file for preprocessor directives.  Note that this code hasn't 
changed since 2006, so I'm a bit confused why it pops up now; it might 
be the Makefile changes (I have had a hard time to not get the specfile 
to recompile too much.)

The biggest problem is that the code is quite frankly littered with 
these, and changing them all would be a pain.  I'm wondering if it is 
the -std=gnu99 which is causing the trouble; if so there might be a sane 
way to deal with it.
