I think the problem is not on GCC .... but the new pycxx installs header files in a different place ... they're now in /usr/include/python2.6/CXX/ but the #includes specifies something Python2 and Python3 ... pycxx seems to be broken ...?!
the real problem is bug 280732
I'll try the fix in bug 280732 to confirm.

I posted a patch to bug 280732 to resolve the problem. *** This bug has been marked as a duplicate of bug 280732 ***
