- GST_CHECK_MPEG2DEC macro - checks for mpeg2dec in /usr/lib.
Original commit message from CVS: - GST_CHECK_MPEG2DEC macro - checks for mpeg2dec in /usr/lib. If not found then checks for mpeg2dec in /usr/X11R6/lib. This macro is needed because mpeg2dec depends on X11R6 libraries and as FHS states, it should be placed in /usr/X11R6 tree but some distros do not care and put mpeg2dec into /usr/lib. It depends on CHECK_LIBHEADER macro.
