Note that wildcard expansion is not performed inside quoted strings.

Also, for recent versions of FFMPEG, the #include directive in
gsd_img_mpeg.c:

	#include <avformat.h>

is incorrect. The directories are now part of the header name, so it
should be:

	#include <libavformat/avformat.h>

The directory containing the libav* subdirectories must be in the
include path.
