[GRASS5] release branch testers wanted (tarball provided)

[Markus Neteler]

As a follow-up:

my build-script now compiles separated a 24bit PNG driver:
http://mpa.itc.it/markus/tmp/pngdriver24_i686-pc-linux-gnu.tar.gz
(65kb)

Installation (PNG driver upgrade from 8bit to 24bit):
1. start grass5
2. cd $GISBASE
3. mv driver/PNG driver/PNG.8bit
4. tar xvfz pngdriver24_i686-pc-linux-gnu.tar.gz

I had to hardcode library paths inside, please let
me know if you get it working (ldd may help).
