Yes gcc does use the bison parser generator, look at
http://gcc.gnu.org and simply download the complete gcc source, you'll find 
in example the gcc bison file for C language in the file gcc/gcc/c-parse.y 

However gcc does not use the flex scanner generator They use their own 
tokenizer/preprocessor. 

So bison yes, flex no.
