We currently do not build, nor test, GLib on QNX. If you're willing to
set up and maintain an automatic CI system that verifies we won't
unintentionally regress on that platform, we'd be very happy to help.
Additionally, if you're willing to help us out on ensuring that GLib
works appropriately on QNX, by fixing regressions and implementing
functionality that is platform-specific, then it would be great.
