Subject: Add minimal support for QNX to configure.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/229251afd85b3fa1bd5c923c7f72262f8c092c3b?ds=sidebyside

Add minimal support for QNX to configure.

Recognize QNX and define __QNX__ under it.

Don't use -lpthreads as the thread functions are in libc under QNX.

Use wxX11 by default.

See #11790.
