This seems like GCC *does* compile the program as C++: it uses the C++ 
include directory in lang/cxx.  So your problem is elsewhere.

Can it be that you mix headers from GCC 2.7.2 with binaries from GCC 
2.8.x?

Since the problem is in the headers, there's no use in posting the source 
of the program: GCC doesn't complain about the source at all.
