The problem being probably that on a Windows machine, "INSTALL" and 
"install" are the same file. I have renamed the file to install.txt (no 
cvs update of course!). Done everything again:

In my "Program Files" there is indeed no directory "FFmpeg" and there is 
a file named FFmpeg which has the same size as avformat.dll.

Since you're working on the build system I wont attempt to patch, it 
would only cause conflicts.
