Most of the things that you reported in that message are bugs in Bison
that have been fixed in CVS as of today, but the above message doesn't
appear to be a Bison bug.  Bison can no longer be built by a K&R C
compiler; it requires C89 or later to be built.  The compiler 'cc
-mips3 -O2' on SGI IRIX 6.5 apparently treats "#error" as a
non-serious error (exit status 0).  I don't think the C standard
allows this.

Perhaps you can fix the problem by passing an option to 'cc' that
tells cc that '#error' should cause a nonzero exit status.

Thanks for your bug reports, by the way; they've helped with Bison
porting.
