Comment (by KSHawkEye):

 Replying to [comment:7 dbuitenh]:
 > The problem is that configure should be calling the prefixed dlltool,
 and not "lib.exe". Libav's configure does this, but FFMpeg's does not, for
 some reason.

 Looks like they use:

 {{{
 SLIB_EXTRA_CMD=-'$(DLLTOOL) -m $(LIBTARGET) -d $$(@:$(SLIBSUF)=.def) -l
 $(SUBDIR)$(SLIBNAME:$(SLIBSUF)=.lib) -D $(SLIBNAME_WITH_MAJOR)'
 }}}

 I second that we move over to dlltool if it can be used to create the .lib
 files.

 I now recommend a cross compile environment to people wondering how to
 compile FFmpeg, and installing wine+Microsoft C++ Redistributable
 packages+lib.exe is a lot more work than simply using a MinGW-w64 dlltool.

 If dlltool can create compatible .lib files, I strongly suggest using it.
