OK, i've made some testing (had to install WinXP inside VirtualBox, but 
now i can use MinGW/MSYS!). Indeed --enable-static --disable-shared 
couple doesn't works anymore - only ffmpeg.exe gets built (though it is 
static indeed).
To get static dlls you have to configure with --enable-shared 
--disable-static (maybe with --enable-static it works too, didn't 
checked that one), edit config.mak and add "-static" to SHFLAGS along 
with "-shared", which is already there. This way you'll get every dll 
built statically.
