Jim Roskind has a ANSI-C and C++ grammar and therein contained is
"skelgrph.c", a patch for Berkeley YACC which produces a nicer
output when used via "yacc -t". Maybe this might help.


You can find Jim Roskinds grammar:
Via "ftp ics.uci.edu" in "pub/c++grammar1.1.tar.Z", Berkley yacc is also
there ("byacc.tar.Z").
