anybody on the developer team knows their way around cpp?

[R A]

i want to add a feature to gcc's c preprocessor.
it's explained here:

but i haven't the time get to know the internal workings and subtleties of libcpp. it'll take me days, at least, before i have a good knowledge of it. then doing the necessary changes and debugging it, would be even longer.

so is there anybody out there that knows their way around this component of gcc? help?
