I don't think it would be good to drop it because popt is only installed by
default on Linux and cygwin (at least of the types I build) and would make
for more trouble for people on all other platforms.  I haven't run across
hardly any other packages that use it, either, otherwise it would be
worthwhile to install popt as a package on its own on all the platforms I
support.
