yacc/bison should be just fine. There are quite a few tools for building 
compilers available, like http://www.antlr.org/ or look for a summary at
http://www.thefreecountry.com/programming/compilerconstruction.shtml.
Usage with KDE CVS apps should be no problem as the generated C/C++ can be put 
into CVS (That's an exception of the rule: No autogenerated files!).

Personally I would prefer the Spirit C++ Parser from the Boost library, as 
this doesn't need any preprocessor, but uses the C++ compiler for parser 
generation; you write your grammar directly in C++. Unfortunately,
KDE supports compiler which seem to not be able to compile with Boost.
