I went through the c++ parser and added support for fixed point there.
 Everything seems to be working, and I am able to use fixed-point
numbers in c++.

The c++ parser is kind of complex and it is possible I missed
something.  I would love to get feedback on this patch, and hopefully
it can get committed to gcc.
