Comment:

 Either reverting the current bison port to 2.7.1 or creating a separate
 port of that version would work for me (as a webkit-gtk maintainer) but if
 bison (3.0) and bison2 would conflict then I think the utility would be
 questionable.

 Bison1 is seriously outdated and has no current dependents so should
 probably be removed.

 A quick check of bison dependents shows 93 at this moment.  I'm sure that
 more than one uses the deprecated features that
 are now removed in bison 3.0 (#39923) although I haven't tested them all.
 And there is no evidence that any port actually requires
 bison 3.0 at this point.

 So my vote overall would be to revert bison to the previous 2.7.1 version
 until the impact of upgrading to 3.0 is evaluated
 with respect to its current dependents. Of course, I would defer to the
 bison maintainer as to his preferred resolution but encourage this to be
 handled as soon as possible since the breakage in webkit-gtk blocks a
 number of other ports. To start, these include gimp2, epiphany, yelp,
 devhelp and the many other GNOME ports that depend on yelp.
