This system currently has :

$ dpkg -l | grep gcc
ii  gcc            2.95.4-8       The GNU C compiler.
ii  gcc-2.95       2.95.4-0.01100 The GNU C compiler.
ii  gcc-3.0        3.0.2-0pre0109 The GNU C compiler.
ii  gcc-3.0-base   3.0.2-0pre0109 The GNU Compiler Collection (base package).
ii  libgcc1        3.0.2-0pre0109 GCC support library.


Using 'apt-cache show gcc' reveals :

Version: 2:2.95.4-8
Provides: c-compiler
Depends: cpp (>= 2:2.95.4-8), gcc-2.95, cpp-2.95
Recommends: libc-dev
Suggests: make, manpages-dev, autoconf, automake, libtool, flex, bison, gdb
Conflicts: gcc-doc (<< 1:2.95.3)

The gcc package conflicts with the -doc package that is of the wrong
version.  The gcc-doc package that shows itself available on this
system is version 2.95.2-20.  

I think the 'gcc' package is just a simply-named package to provide
the current default version.


Try running
    apt-get remove gcc-doc
    apt-get install gcc-3.0 <other gcc3 packages you want>

You can put a '-s' option after the 'apt-get' to see what apt will do
if you run the command for real (without the '-s' option).

HTH,
