tried it, contacted the OP no answer
I got stuck on 1.3 already
1.3. Ensure that mingw-builds bin folder is set in your PATH environment variable. On Windows 7 your path should look something like:
C:\mingw32\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\
I go to c:\ming32\bin and there is no systemroot
2. Download, unpack and build required dependencies.
I'll save them in c:\deps fold
what does that even mean?

Patch %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\
Patch recplace with C:\mingw32\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\
