Trying to build an application that was built on Qt 4.4.3 on windows.. but I'm getting a ton of link time errors. Is this because of a version issue?. If so where can I download the previous version.

It's very unlikely that anything built with 4.4.3 will fail to build with 4.6.3 or 4.7.0. If it does, it will most likely fail in compilation because of API differences, and not at link time. It looks like the GCC C++ support library is not being found or you are linking a library built with a different version of GCC and/or Qt . Are you using the Nokia provided SDK or have you built MingW for yourself? Have your cleaned the project and any libraries, rerun qmake, and built from scratch?

Ok I followed as you suggested and decided to use Qt Creator to do this, as
it has the right commands and it worked. I was wondering though, I want
to be able to build other things using my own cygwin make in other projects,
and at the same time I want to be able to build using the mingw32-make for this
project without QtCreator. I am not sure what to do, because if I have
C:/Cygwin/bin in my path, mingw32-make calls the wrong g++, and I get all those
ugly errors. What would you suggest for this?

Manipulate the PATH variable so that the proper g++ is always first in the path. If you want to force a specific g++, you can redefine QMAKE_CXX and similar for your projects.
