You can look for the GNU C compiler. It has a Yacc parser (or a 
Bison parser, Bison is a yacc clone). But you might get problems 
with the copyleft.

I have seen a file in german Fidonet, pretending to be a C++ Yacc 
parser. Haven't loaded it, but since C++ is a superset of C it 
should help:

The description line (that's all I know):

YACCPP.ZIP 49942 05-09-90 YACC - Grammar for ANSI-C and C++

Available in german Fidonet node 2:507/205. Tel-Nr 49-231-47126.
