Just small update i think i have got most of C code working now, but working on C++ generation again its all shaping up to look pretty usable. I wonder by the off chance is there a python library that can parse the C preprocessor if anyone knows or not i am looking at https://code.google.com/p/pypreprocessor/ to try and parse cpp as this information is lost at the Middle-end level in GCC where the plugin runs.
