  AFAICT QuantizeBuffer was available before 4.2 and there
it disappeared from the lib. Later in 5.0 it was re-introduced
as GifQuantizeBuffer.

  Strange. Can you post the first line of config.log and
the complete sections of the gif tests?

  I am puzzled how this change can make things worse. If
it does, it's essential that I understand why.

  Maybe you can find out if the version of GIFLIB you were
trying to build against was patched (e.g. by the packager).

Thanks for testing,
  Alexander
