There is a common misunderstanding that only VS2003 can be used to compile extension objects for Python 2.5. Don't believe it. There is no Python limitation for the compiler. There is a Python limitation for the C runtime (crt), but only if you share crt objects with Python. That is, if you e.g. open a FILE* pointer in C, create a Python file object from the pointer, and then read that file in Python. In this case Python would do a fread on the pointer, and it is your responsibility to make sure the same crt DLL does the fopen, fread and fclose. If you don't share any crt resources with Python, there is no limitation on the crt either. If you do a malloc and a corresponding free in C, it does not matter what crt you use. It may even be used by Python objects in the meanwhile. mingw (gcc, gfortran) can be used freely, and afaik is used to compile the official NumPy and SciPy releases for Windows. The gfortran team has made a binary installer for version 4.4 available in their Wiki. When using mingw you have to link with the the same crt as Python if crt resources are shared. That is -lmsvcr71 for Python 2.5 and -lmsvcr90 for Python 2.6. If crt resources are unshared, link with whatever crt you want.
