Note that we are not really supporting GCC pre-3.x anymore. If  
possible w/o too much hassle, we try to fix issues with it, but other  
than that, it is *strongly* recommend to use 3.x or 4.x.

Odd. There is no "\." and no "\B" nor "\P" in the source. Maybe the  
"." is substituted for something else... Could it be a line ending  
problem? Seems unlikely, though.

Have you tried to just run the preprocessor on the file, then review  
its output? That provide some more insight on the issue.

It's very unlikely that the order of the #defines has any effect on  
this.

Maybe the indention of the #define / #ifndef is causing problems,  
although that would surprise me, too.
