This appears to break setups like RHEL 6 where we still use bison 2.4.1:

/usr/bin/bison --yacc --name-prefix=__gettext --output plural.c plural.y
plural.y:46.18-21: syntax error, unexpected identifier

We don't seem to document or test for any particular version of bison, though I
see the shipped plural.c file is still from bison 2.7.

It would be nice if this actually continued to work with the older bison.
I just changed that line to "%define api.pure", which works, with some -Wundef's,
but honestly I have no idea what I'm doing. :-)  Equivalently I can just touch
the shipped plural.c to avoid running bison; again we do get -Wundef's, though.
