I guess a bigger change.  If you do:

yacc -p c_ c-exp.c

you'll end up with a .c file that contains:

#define yyparse c_parse

but since c-exp.c already defines a function named c_parse, that
becomes problematic.

But I just realised that you can work around the problem, by doing

#undef yyparse
#define yyparse c_parse_internal

So never mind.
