Subject: The new REQUIRE token introduced by change 25599 must be
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=2051588124b1d9accc9aeb526746bb222cea5170;p=p5sagit%2Fp5-mst-13.2.git

nonassoc, just like the UNIOP token it's patterned after.
(While we're at it, allow to use bison 2.1 to regenerate
the parser files.)
