I don't know, and I didn't find anything in the documentation that
addresses this question.

If it's not possible, and you only call 'yyparse()' once,
then I think you might as well use a globally or statically declared
pointer to point to the object referenced by your parameter. If you
have multiple calls to 'yyparse()', and it needs to be thread-safe,
then I suggest using thread-specific data containing a pointer
to that object (see "man pthread_key_create"). It might also turn
out to be advantageous to use a pointer to a pointer.
