AMD64 version of GNAT Ada compiler broken due to libthr

[John Marino]

Yeah, that's kind of what I was getting at.  Would this patch get into 
FreeBSD 8.2, and would that mean that GNAT would start working properly 
starting with FreeBSD 8.2 if that happened?

I guess that also means the other BSD's have been allowing executable 
stacks all along.

Thanks!
