  // On 64-bit Windows, there's only one calling convention,
  // so there is no difference between MSVC and GCC. On 32-bit,
  // this isn't true. The convention that GCC needs to use to
  // even build AviSynth+ as 32-bit makes anything that uses
  // it incompatible with 32-bit MSVC builds of AviSynth+.
  // The AVSC_WIN32_GCC32 define is meant to provide a user
  // switchable way to make builds of FFmpeg to test 32-bit
  // GCC builds of AviSynth+ without having to screw around
  // with alternate headers, while still default to the usual
  // situation of using 32-bit MSVC builds of AviSynth+.
  
  // Hopefully, this situation will eventually be resolved
  // and a broadly compatible solution will arise so the
  // same 32-bit FFmpeg build can handle either MSVC or GCC
  // builds of AviSynth+.
