[GRASS-dev] Region problems in grass 6.3 (maybe also 6.1)...

[Michael Barton]

I can confirm this. There seems no way to satify g.region. We've set the
WIND file manually and still get the same error.

We did a make distclean and recompiled today (15 August) and still have the
same results. This is on an FC4 32bit system.

I tried the identical actions on my Mac, using 6.1.0 binaries compiled 12
August and had no trouble at all.

Did something change with g.region? Could this be due to the parser changes
that Markus mentioned earlier today?
