It turns out that (under circumstances) Bison 1.875 procuces code that
doesn't compile with gcc >= 2.95.  The culprit is code that should
suppress gcc warings.  This code is removed/fixed in Bison 1.875a (see
ftp://alpha.gnu.org/pub/gnu/bison/) or Bison CVS (see
savannah.gnu.org).

You may upgrade Bison, or use the patch below.

Greetings,
Jan.
