Rob/Andrew -

Tested my usual builds with Andrew's patch and then rendered a Gif Sequence with no problems. Not sure if that includes all necessary tests concerning Gif but hope so. I would have liked to test by building without thirdparty but I do not have sufficient disk space to install all of the Operating System libraries to use instead of the thirdparty ones. It has been checked into GIT with the following commit:

commit 0bb5444770e3db55113e4c012d0a1074e30f4475

Thanks to Rob for pointing out this deficiency and Andrew for addressing.

As aluded to, out in the wild even the consistent library version number
has inconsistent, interfaces between sources. Until upstream gets their
act together, the prudent thing is probly to test compile and set flags
as AR suggested.

Please let me know when the patch is pushed and what commit it exists
under and I will merge and test for Debian 13.
