Thanks Jef. So, fixing the memory issues in grass code isn't
avoidable. I'll go on with this (after g.proj, db binaries, v.in.ogr,
etc.), because probably this will solve the problems that users are
facing from within QGis (various crashes when using the grass plugin).
So the real limitation for the end-user, is the possibility to use the
complete wxgui (digitizer, nviz), but as Martin is working on this I
think this isn't an issue.

The build system is not strict for the end-users collegues: "I want it
to work, I don't care how they made it!". This is my boss phrase :)
