SVN 26779
User has to manually edit the Makefile to add rules for the following:
libavcodec/libavcodec.a:
$(MAKE) -C libavcodec
libavformat/ .......
libavutil/ ..........
libpostproc/.............
libswscale/libswscale.a:
$(MAKE) -C libswscale
Makefile works fine in Linux. Just bombs in MingW with message saying no
rule for the above.
