If we use strverscmp(), it will be sorted in a more reasonable
way. We could copy the gnulib version on systems without glibc.
Life is too short for writing configure checks by hand, though; I
will add this to the end of my wish-todo list. If somebody wants
to volunteer, be my guest.
I'm CCing Eric in case he has suggestions that would help import
the gnulib module in an easy way.
