It seems prefix et al. have nothing to do with the failure to build 
libavutil. What I have is this in my environment:

LIB=C:\Program Files\Microsoft Visual Studio .NET\FrameworkSDK\Lib\

Where that comes from is a mystery... I have unset it and relaunched 
configure, now it seems to loop, but there is another CPU hog on my PC 
now, so its hard to be sure. Stay tuned, I will report as soon as I have 
more info.
