Possible Solution:
==================
A "set of patched driver files" is (hopefully) not really necessary. I
installed the "stable" MinGW 5.13 on my Vista laptop with gcc 3.4.2 and had
the same issue. I got it to work by adding this to my path:

set PATH=C:\MinGW\bin;C:\MinGW\libexec\gcc\mingw32\3.4.2;%PATH%

This is in a windows cmd prompt. Translate accordingly for use in msys or
cygwin environments... (Or perhaps for gcc 3.4.5...)

HTH,
