I cannot tell wether you installed from source or from binary debian
packages. If the latter, also try asking in debian forums about
possible package problems; gcc is not friendly to packaing tools
like deb and rpm. (Worse, linux distros like to slice up gcc into
different packages after the binaries are built, something that as
far as I know was never intended to work.)

First, ensure that libglut was built by gcc 3.3 . If it was built by
3.1, 3.0, 2.96.x, or 2.95.x, it will not link with c++ code built
by gcc 3.3 .
Second, use 'g++' to link, not 'gcc'.
I don't know if these things will fix your problem, but please try
them and post again.
_Unwind_Resume_or_Rethrow is defined in <prefix>/lib/libgcc_s.so
Usually, g++ will figure out that you need this library and
automagicly link it in.

[snip]
I note gcc 3.3 is installed with --prefix=/usr . What --prefix was used
for 2.95, 3.0, and 3.2 ? Each version of gcc should be
installed with a differnt --prefix. For 3.0+, you can check
--prefix by running gcc -v (as you did above).
