As far as I know, in the Ports tree there are only:

editors/emacs
editors/emacs-devel
graphics/OpenEXR
multimedia/vdpau-video

which use it in an ill-conceived (and now probably unnecessary) test
for thread libraries.  However, there are many more instances within
the configuration scripts of various port distfiles, and I do not
think that all of these are protected by tests for gcc*.
