These files are updates or addons to the existing VL-2.5 system. Cups and gcc
are addons. GCC-3.2 installs into the /usr/local directory so you can use it as
a supplimentary compiler. In other words when doing ./configure for a source
file you need to do this first:
CC=/usr/local/bin/gcc CXX=/usr/local/bin/g++ ./configure
then compile as normal
If it doesn't compile properly then leave out the CC= CXX= and it will default
to the base gcc-2.95.3 compiler.
