Does this require some version check in configure to be added as well?


No. We ship the header ourselves, rendering a version check in configure moot. What configure checks for is the presence of the dynamic loading functionality that the library depends on.

The actual version compliancy checking occurs inside the AviSynth demuxer: version 2.5 is checked for at load time and rejected. This patch adds a check for whether we're using AviSynth+ by detecting the presence of the planar RGB functions in the library, and if that's false (in other words, 2.6 is the one being used), it stops 2.6 from even attempting to use the two functions that it doesn't have.
