gcc.gnu.org provides the source code for gcc.
Binaries for win32 are available from www.mingw.org or 
www.tdragon.net/recentgcc (these are also referred to as TDM gcc)
There is no specific version for windows vista.
If you want a 64bit compiler, look at 
http://sourceforge.net/projects/mingw-w64/.

Installation is done manually (e.g. by downloading the necessary binary 
packages and unzipping them).
http://www.tdragon.net/recentgcc/ provides some installation guidelines.

You'll need at least
 gcc-core-bin
 gcc-g++-bin
 gcc-gfortran-bin
 win32api-dev
 mingwrt-dev and -dll
 binutils-bin

You should find the mingw32 comiler in the mingw32/ subdirectory of your octave 
installation path.
Octave 3.2.2 was built with the 4.3.0-2 TDM (dw2) compiler.
Octave 3.2.3 and later are built with the 4.4.0 mingw32 compiler.

What are you trying to do?

If you want to compile .oct files the you'll need the compiler that was used to 
build octave with. 

If you want to compile octave itself you can choose the compiler you want. I 
suggest to use 4.4.0 or later.

Bleeding edge (i.e. 4.5.0) compilers are available from the mingw-w64 project 
(they also provide 32bit-targetted versions) - these are of course still under 
development and not yet released as stable.
