If you mean your "build as shared then link manually" - no, didn't tried.

I mentioned libogg and libvorbis as an example. This list also includes 
libfaac, liba52 and libgsm. I'll think of excluding ogg, vorbis and mp3 
support from my builds though, that's a good point.

My problem is my MSYS/MinGW collection. I'm suspecting it has a few 
buggy modules in it. They are making something with my PC - after 20-30 
runs through configure script Windows starts acting funny - refuses to 
launch applications (without any sensible error messages - it's just 
crashes), doesn't shows menus when it should, a few applications won't 
draw their contents anymore (FireFox for example), etc. I think it's 
memory or pagefile corruption/pollution, but i may be wrong. Anyways, 
the only fix i found is to reboot - which is something i'm trying to 
avoid. That's why i'm not making ffmpeg builds anymore.
