Short answer:  no.

Long answer:  yes, you have access to the GCC source code and you could
munge that to make it do what you want.

You'll have to write your own preprocessor.

Fortunately, there is a C/C++ preprocessor called Wave already written by
Hartmut Kaiser using Boost Spirit that you could use as a starting point and
customize from there.

http://spirit.sourceforge.net/repository/applications/wave.html

Boost Spirit is a EBNF-like representation in C++.  (Technically it is an
object oriented recursive descent parser generator framework implemented
using template meta-programming techniques.  The C++ alternative to using
flex/bison or lex/yacc.)

Boost is a grab bag of incredible enhancements to the Standard C++ Library.
