[tim-6] MAXTABLE and suffix comment

[Tim Van Holder]

Doubles MAXTABLE (and align the define) to allow for screwy grammars.
Also adds a FIXME about suffixes on DJGPP; IMO, bison should only
settle for the DOS extensions (_tab, .sth) if the standard ones can't
be used.  For DJGPP, this amounts to a run-time decision.

2002-01-06  Tim Van Holder  <address@hidden>

        * src/system.h: Double MAXTABLE; some (rare) grammars require
        it.  Add a FIXME for the DOS extensions; their use should not
        be hardwired for DJGPP.
