Without having looked into details, something in GCC seems to have changed which
silently breaks gthr-rtems.h.

Indeed, things rarely break without reason. :-)

Grrr.. looking back through the old mail and mail lists, that was indeed the
intent when this was first mentioned. I just added a new GCC patch and the
corresponding RTEMS patch (for reference). What do you think of them?

pr19399-try2.diff looks good to me. I've just launched local test-builds,
nevertheless, OK to commit, IMO.
I haven't looked into rtems-gxx_wrappers.diff, yet.
