I deleted the message asking about passing a parameter to the `merge' function, so I can't reply directly.
There may be a better way of doing this, but a workaround might be to use thread-specific information, assuming each call to `yyparse()' has its own parameter object and each parameter object is associated with a single call to `yyparse()'. With some care, it might be possible to use thread-specific information even if these conditions don't apply. However, I neither know how the merge facility works, nor how it would interact with threads. If you're using LinuxThreads (which is included in the GNU Standard Library for C), see the man page for `pthread_getspecific'. I believe it should also be possible to use a different library that implements POSIX threads, though. If you want to see an example of using thread-specific information, my code is available at http://savannah.gnu.org/cgi-bin/viewcvs/3dldf/3dldf/Group/CWEB/ I define `struct Thread_Info_Type' in the file `pspglb.web'. Otherwise, I recommend David Butenhof's book _Programming with POSIX Threads_.
