To this can be added that an implementation of GNAT using Linux naitve
threads doesn't fully support Annex C & D of the Ada Reference Manual, as
the Linux threads are not fully in conformance with POSIX threads. There is
an alternative threading implementation from the Florida State University
(FSU) that fully support thouse two annexes.
