There is the library you mentioned and the argp implementation from
gnulib.  I personally prefer gnulib, because we don't have to worry
about copyright at all in this case.  But I agree, including it so
things work on BSD is prefered.

I assume you noticed grub-emu isn't compiled by default.  It makes the
situation a bit easier when using BSD.  Although for a good port we
need some argp implementation on BSD.
