Upcoming: update gcc to 4.1.2 in moonbase, gcc3 module for fallback

[Kok, Auke]

All,

I intend to update gcc to version 4.1.2 within the week. As far as I can see, 
there are no blocking bugs that prevent a normal system from working just fine 
with this new version, and most of the developers have already been running 
their entire systems on gcc-4.x for a loooong time.

For those who wish to stay on gcc-3.x, there will be a gcc3 module available 
from tomorrow or so that you can install at any time to prevent gcc from being 
updated to 4.1.2. the gcc3 module will replace the current 'gcc' module as the 
default if you install it (it will uninstall the 'gcc' module) but work exacly 
the same.

Cheers,

Auke
