 # - FFmpeg 3.3 doesn't cross-compile correctly, qTox build fails when linking
 #   against the 3.3 FFmpeg. They have removed `--enable-memalign-hack` switch,

-# - Toxcore v0.1.9 doesn't cross-compile to Windows due to a linking order
-#   issue in monolith_test https://github.com/TokTok/c-toxcore/pull/564. It's
-#   fixed in master, so we just wait checking out a stable master commit point
-#   until the next release. Once the next release occurs, we will be checking
