The new ffmpeg-1.0 comes with the headers libavutil/time.h and 
libavutil/log.h.  These overrule /usr/include/time.h and 
minidlna-1.0.25/log.h due to the priority of '-I' set in the
Makefile

CFLAGS = -Wall -g -O3 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 \
	 -I/usr/include/ffmpeg \
	 -I/usr/include/libavutil -I/usr/include/libavcodec -I/usr/include/libavformat \
	 -I/usr/include/ffmpeg/libavutil -I/usr/include/ffmpeg/libavcodec -I/usr/include/ffmpeg/libavformat

Here below is a patch removing the need for these search
directories.  Backward compatibility could be guaranteed via
'-I/usr/include/ffmpeg'.
