This question pops up from time to time.

The work around is to get byacc (Berkeley yacc).
Having the source code allows you to set the number of symbols
availible in the symbol table, and simply recompile, if
necessary. No changes are needed to compile this package on the 3b1.
As a bonus, byacc operates faster than the stock yacc.

You can get byacc at some of the archive sites around; 
one source is skeeve.

Best of luck,
