Unless 2011 has change the default run-time library,
When GNAT is installed the RTL is rts-native. Native uses the
thread package of the underlying OS.
"FSU threads library", "pthreads library" (Solaris only),
"Zero-Cost Exceptions" ("ZCX"), and "setjmp/longjmp"
("SJLJ"), are optional if compiled, by using the "--RTS="
command line option.
Note: "FSU threads library" provide a completely accurate implementation
of Annex D. Since "Glade" was replaced, not sure if GNAT, still provide
a true implementation of Annex D.
