OK, I spoke a little too soon.  Looks like gcc 3.2 has some problems.  gcc 
2.95 never gave me any trouble.  I have precisely the same problem with 3.2 
when I try to set a breakpoint in cs_grammar.y - it tells me that the file 
doesn't exist.  Looks like a bug in gcc, or perhaps recent gdb's.

It does not appear to be in pnet.  You can work around it by turning off #line 
and then, but that isn't a permanent solution, and won't be checked into CVS 
because it will interfere with debugging on 2.95 systems.  If someone knows 
of a better work-around please step up and tell me.
