not in the sense of actually combining the code bases, I'd say, but
certainly comparing all three.  gnu is guaranteed to be better
maintained/kept up to date.

True: we can only take parts that are in POSIX.1-2008/XPG7, obviously.
But checking for differences is still in order, I believe.

Right, except for the fear that the code has partially bitrotten.  It's
up to Jonathan, of course, to decide if we're better off keeping gnu,
dragonfly (better renamed to bsd to match actual use) and
ieee-1003.1-2008 separate or update/rename the dragonfly code to work on
both the BSDs and POSIX.1-2008 systems.
