Latest news:

unset LIB
make distclean
./configure --enable-shared --disable-static --enable-memalign-hack
make

it goes as far as:

cp -p ffmpeg_g.exe ffmpeg.exe
strip ffmpeg.exe
c:\mingw\bin\strip.exe: ffmpeg.exe: File format not recognized
make: *** [ffmpeg.exe] Error 1

Why, no idea, could be a bug in my mingw version. But I see that the 
.lib are present, and the dll sizes show clearly that avcodec is no 
longer inside avformat.dll:

$ ls -al */*.dll
-rwxr-xr-x    1 michel   Administ  8149751 Jan 30 16:29 
libavcodec/avcodec.dll
-rwxr-xr-x    1 michel   Administ  1231063 Jan 30 16:30 
libavformat/avformat.dll
-rwxr-xr-x    1 michel   Administ    53370 Jan 30 16:21 libavutil/avutil.dll

So:

"Here are the votes the Belgian jury. Germany: 10 points!" (Loud cheers)

Of course, I still have to sort out my shell init files under windows; 
since I have both cygwin and mingw installed, and moreover the config 
has been tweaked so I can rsh from a Linux machine to wrshdnt which 
invokes the cygwin bash which launches MSVC...
