Awesome. In the past I discovered that if I delete the inappropriate
linker pragma in i-forbla.adb and link with -largs to the BLAS and
LAPACK libraries in the OS X frameworks that I could work around this
problem. But this is better. Following your lead, I moved the newly-
made i-forbla.o and i-forbla.ali into

/opt/gnat-gpl-2009/lib/gcc/i386-apple-darwin9.7.0/4.3.4/adalib

I then moved /opt/gnat-gpl-2009 to /usr/local/ada-4.3 which is where
the Xcode Ada plug-in expects to find a compiler. I also moved your /
opt/gnu/ to /usr/local/gnu.

I can now compile a small program that uses Real_Vector etc. and has a
non-blocking Get_Immediate without any compiler switches using Xcode
with the (ever-brittle) Ada plug-in. 8o)

Trying to use the GUI debugger within Xcode,
(Apple version gdb-768) (Tue Oct  2 04:07:49 UTC 2007)
is mostly successful but it bombs with SIGBUS when trying to single-
step past a Put_Line.

I have also applied the fix to AdaCore's GPL 2009.

Unfortunately, with the new set-up, building PLplot (to which I wrote
Ada bindings) now results in the linker complaining of some dylibs,
"file is not of required  architecture."
