Creating intelligent search 'n replace for C/C++ source?

[Jacob Ole Juul Kolding]

Hello List

I'm a total newb regarding all things bison/yacc but I think it's the 
tool for my current problem at hand.
I have a rather large code base written in C/C++ where I need to replace 
some fundamental classes
and all references to function call from other classes/functions.

All I need is a program that can parse the source and replace all 
instances of
classes and functions including arguments based on a simple 2,3 column 
text file.

Can anyone point me to relevant examples or share ideas on the subject?

Best Regards
Jacob
