[MITgcm-devel] Genmake2 in good form

[Chris Hill]

I think morphing to autoconf is a sound strategy but it should come after

 1 - testing is back in action on all platforms.
 2 - r2 is finished.
 3 - we have another big injection of cash.

Meantime I would like to stick with what we have which I think works fairly
well.
