As part of the update, it is now possible to test 32-bit GCC builds
of AviSynth+ with FFmpeg by using the AVS_WIN32_GCC32 define. Due to

Windows, this is unfortunately necessary.

Could not be used in apply_dependent_coupling because of alignment issues.

Ever since 59ad5046, the demuxer expects its seek arg to be PTS
and adjusts internally to search index by DTS.
