My previous replies didn't show up. Something to do the .announce
group? I'll trim that and try again. Sorry if they show up eventually.

Two issues:

1] why does both gmpy 1.11 and gmpy 1.11rc1 both reply

>>> gmpy.version()
'1.11'

Aren't these different versions? How are we supposed to tell them
apart?


2] Is it true that the only changes since 1.11rc1 are not
   applicable to me since

   - I'm not using Windows
   - whether it recognizes GMP 5 is moot as GMP 5 cannot be
     compiled on a Mac (according to GMP site)

Is it possible GMP's problems with getting GMP 5 to compile
are the same ones I had with 3.1 on Snow Leopard? (They bemoan
not having a set of every Mac system.) Think it would behoove
me to try it?
