Subject: Re: ports/128603: textproc/flex has too small capacity

Here is a stab at an optional patch to textproc/flex.
Unfortunately there doesn't seem to be a way in the OPTIONS system to
ask the user for a number.
Therefore I used a mixed approach, where the OPTIONS are used to turn
the patch on and off, and where the user can optionally set
FLEX_NUMBER_OF_NFA_STATES to the desired value (somehow). I found using
/etc/port.conf useful, while putting options in between
".if ${.CURDIR:M*/textproc/flex}" and ".endif" lines.
