If I understand you correctly, you currently have GCC 2.9x, and you want 
to use GCC 3.3.

Much depends on your distribution of Linux. As far as I know, every 
Linux dustribution installs a version of GCC, so you're probably using 
whatever came from whoever (SuSE, Red Hat, Debian, etc.) packaged your 
Linux. You may want to check with your Linux distributor; it's likely 
that an update to your Linux installation will automatically upgrade 
your GCC.

Some Linux distributions include both GCC 2.9x and GCC 3.x, giving one 
or the other a special name (say, gcc-3) or using symbolic links to set 
which compiler you're using.

If your Linux vendor does *not* have a newer version of GCC, you have 
two choices:

1) Change Linux distributions (which may be the easiest solution for a 
Linux novice)

2) Download the GCC source code, compile it, and install it yourself.

The main gcc web site (http://gcc.gnu.org) has relatively clear 
documentation on configuring, compiling, and installing gcc from source.
