PATCH: configure warnings for libjpeg and giflib

[Marcus Meissner]

Hi,

Another testballoon.

Will print this:

*** No JPEG support: jpeglib.h not found, OLE automation cannot use JPEGs.
*** To add support, install the necessary jpeglib development package,
*** usually called libjpeg-devel or jpeg-devel.

*** No GIF support: gif_lib.h not found, OLE automation cannot use GIFs.
*** To add support, install the necessary giflib development package,
*** usually called gif_lib-devel or libgif-devel or libungif-devel.

Ciao, Marcus

Changelog:
	Add warnings for missing GIF and JPEG support.
