Darwin is a standard build option in GCC; you can buy support for a
Darwin GNAT from AdaCore or you can download the GPL version.
The GCC maintainers don't regard Darwin as a primary target (unlike
Linux). But it hasn't been a stopper so far.
At the moment I think the difficulties arise with Apple oddities and
even bugs: for example,
PR42554[1] is down to Apple's introduction and then deprecation of
"ranlib -c".
PR50678[2] is caused by Apple's stack unwinding having a mistaken view
of how registers are stored after a stack overflow, which only seems to
affect GNAT.
