For reduce/reduce conflicts, one has to generally rewrite the grammar  
or use the %glr feature (see the Bison manual).

There is a Yacc C++ grammar:
  http://www.parashift.com/c++-faq-lite/compiler-dependencies.html#faq-38.11
And one for C:
  http://www.quut.com/c/ANSI-C-grammar-y.html

So you might check them out. Also, there were some discussions  
recently about handling C++ ambiguities in the Usenet newsgroup  
comp.compilers.
