Thanks, I wasn't aware of the BSD getprogname until now.

How about this proposal?

* Change the progname module to use the BSD getprogname naming
  convention.  No sense reinventing the wheel.  That way, programs can
  simply use the system-defined functions on BSD.

* Rewrite the other gnulib code to use the new convention.

* Ask gnulib users to switch to the new convention.

This approach does not address James Youngman's preference for an
arrangement which results in a compilation or link failure if the user
(i.e. software maintainer) fails to initialise things properly, but I
don't see any easy, nonkludgey way around that, so we'll just have to
bite the bullet.
