I run Debian stable with some packages from backports. When I try to install gcc-4.3 (with apt-get) I get an error complaining about a bunch of dependencies which aren't met. However when I look at those dependencies I see that they actually are met. Whats going on?

Thanks for the tips. I did try apt-get install -f, but it didn't need to fix anything, and running apt-get install gcc-4.3 afterwards gave the same output.

But at least it gives me a hint of whats wrong, it seems gcc wants a version of libgcc1 lower than 4.3.6-1. The version on my system is 4.6.2-15. Is it possible to install multiple versions of libgcc1? I couldn't find them with apt-cache search.

You must have had the sid or wheezy repos enabled at some point in time because you have several sid/wheezy version packages. The packages you listed: cpp, cpp-4.4, cpp-4.6, libgcc1, libgomp1 are all at the versions currently in sid & wheezy. The binutils package that you have installed is also a lot newer than the 2.20.1-16 squeeze version. You have version 2.22-4, the sid/wheezy version is currently 2.22-5.
You can try aptitude again. Answer 'no' to the first solution it comes up with and see if it comes up with some other solutions. Depending on what else has been installed & upgraded from sid/wheezy, aptitude may not be able to come up with a solution that doesn't involve removing things.
The only solution is to remove or manually downgrade all non-squeeze packages; Or full upgrade to wheezy/sid. I recommend the former unless you are not skilled at apt in which case you should backup important files and reinstall. Do not mix sources it simply does not work.
Yes you're both right, the packages installed from unstable seems to be the problem. I had to install gcc-4.6 to be able to install the nvidia driver for my card, and I will need gcc-4.6 again if I ever upgrade the kernel. I have now downgraded everything which works but I no longer have access to gcc-4.6. Is there any way for gcc-4.6 and gcc-4.3 to coexist on a system?
