PATCH: gengtype-yacc.y portability

[Loren James Rittle <rittle at latour dot rsch dot comm dot mot dot com>]

Attn: Geoff Keating

I've looked at bootstrap/10452 from my peers on the FreeBSD-side that
have been looking at pulling gcc 3.3 into the system compiler ASAP
after the official FSF release.  byacc is still used to build gcc on
FreeBSD in that configuration.  In the interest of robustness (testing
an implementation against multiple tool chains vs. one improves
overall robustness), could I install this patch on mainline and 3.3?

I rebuilt gengtype-yacc.c with both bison and byacc and studied the
output (diff against the original in the case of bison).  More
importantly perhaps: I verified that gentype output itself was the
same before and after this patch.  FYI, byacc is treating the second
item on the token line as another token to handle instead of the name
to use in the debugging name table.

Thanks,
Loren
