I commit some changes in pygrass (r68138), temporal library (r68139)
and GRASS scripts (r68140) that were on my trunk from a bit...

At the moment the compile chain is not working on python3, so you have
to compile using python2 but then you can use GRASS with python3.
The issue with ctypes (#2708 [0]) is still valid, I've "locally" fixed
changing / with // only for the line: ('__val', c_ulong * (1024 / (8 *

Of course, GRASS with python3 works only in text-mode, no gui.

All the best
