[GRASS5] problems with [rsv].proj

[Markus Neteler]

... sorry to insist... Is there any hope to get
[rvs].proj functional again and to release 5.0.0pre5?

I am not sure if I should try to fix Roger's fixes :-)
(maybe not).
Roger, if you commented the 'datum' entry in PROJ_INFO
(both, and/or target and source location), you could test
if it works for you (to simulate a non-US location).

Thanks,

 Markus
