OK, I made this change to the patch (same URL.)  I left -ly in the
crunch conf too.

OK, thanks - I doubt they will, as it's a bit un-POSIX-like, but who
knows.

Regardless, to help mitigate this sort of confusion in the future, I
made another patch:

  http://catseye.webhop.net/DragonFlyBSD/patch/yacc_man_ylib.diff

This patch adds a brief description of liby to the FILES section in
yacc.1, and adds an MLINK from liby.3 to yacc.1.  Not much, but better
than nothing, which is what we have now.  Any thoughts on this?
