Well, they only work if you are willing to abandon multilibs and to
replace your system's compiler. To me, this is beyond reason.
And .. if you're on a multilib'ed host, life will be even one magnitude

What I said applies to gcc < 4.1.x.
Also remember: Once we should start shipping multilib'ed RTEMS binary
libraries, we will have to drop GNAT/RTEMS unless GNAT finally starts
