Alternative to yacc/lex

I'm working on a compiler rewriting project, for an internally
used 4GL language. The former compiler was of ad hoc type, now
we want to use a neatly structured solution. The compiler must
be portable between many different platforms.


One problem with yacc and lex is that they produce a lot og
global variables (yy...). Since we use light-weight processes
this means that we must forbid simultaneous compilations.
We'd like to put all those variables into a struct, automatically.
Have anyone seen a solution to this problem?


Maybe there are newer, better alternatives to yacc/lex?
