   It would be confusing.  But if it wasn't would it still be maui?  (I 
joke, I think maui/moab are excellent, but they aren't trivial.)

   What I had in mind was that at compile time if getgrouplist existed then 
that method would be selected, unless --without-getgrouplist (or something 
like that) was given to configure.  If getgrouplist doesn't exist or 
--without-getgrouplist was specified, then the build process prints a 
warning about Method 2 being used.

   That's probably too complicated and confusing, but would be the most 
flexible.

   Next most flexible is choosing the getgrouplist option and not building 
that functionality on platforms that don't support it.

   If we could amass a list of maui platforms and assess the availability 
of getgrouplist we might find that it would work in enough places.

   The safest thing, of course, is to assume nothing and implement Method 
2.

   But I'm just opining into the monitor, at this point, as I have neither 
the skill nor time to be productive here.  I think whoever does the work 
gets to pick. :)
