I second what David said: just use the system compiler / linker to produce
a DSO and load that into your process. Anything else is going to be much
more complex.
And, I don't see why you would need Synopsis *and* a custom gcc frontend
(such as gccxml).
You can generate a parse tree (etc.) with synopsis alone, process it either
in C++ or python to generate new code, then call a system (or custom) toolchain
to compile that into a loadable module. If you are doing all this in python
you don't even need to care about ABI compatibility issues.

Not a problem if you don't *link* with gcc code (synopsis is distributed
under LGPL).
