C grammar for perl-RecDescent

Hi!,
I have a need to parse C file from perl (to generate som kind of output,
not a binary).
I loved the phylosophy of perl:recDescent except that it is a top-down
parser... An I dont't have such a grammar for C...
So the question is: is there such a grammar (right recursice, not left
recurvice) for C?
Or:
Is there any parse::RecUp, that is a perl package as great as perl
recdescent for a bottom up parser that would eat-up a usual yacc grammar?
I have read about byacc and yapp, but I really liked the simplicity of
recDescent (no separate lexical analisys, no extern program generation:
just one file and go!)

Thanks for your tips,

/Christophe
