This reverts commit 41af38f3728bd64b80721c44ed1fb019978cbc1b, reversing
changes made to f0fec244ca380b9d3e617ee7b419c59758c8b0f1.
Let's delay this. We have some serious regressions.
Fixes build error: undefined reference to `GifQuantizeBuffer'
that was most likely caused by giflib update in 3605f1285
ABI tracker didn't show removal of this symbol - I don't know,
perhaps we have different build setting, or something.
Here I found no NEWS, ABI tracker seems OK - only minor
incompatibilities in -private headers. Mono stuff builds now.
Configure script complains, that unable to build gif loading support,
but it's a lie -- it builds against libgif 5, which have DGifOpenFile as
well.
