NetRadiant was ported to FreeBSD. Thanks to some rework done by TimePath on the global defines, some part was very straightforward. At some point, some issues faced were the same as the ones faced on macOS, so doing this is one step toward macOS support (which is not usable yet due to a feature missing in provided GtkGLExt).
Also, Crunch was fixed to build on FreeBSD too, meaning the support is complete.
See the merge thread for details about the implementation.
