You might be able to do it for some ideal compiler, but I'd be mightily
impressed if someone managed it for GCC.

Anyway, if someone wanted to use GNAT's streams for an Atmel SAM3X-based
system, they'd want to check them out on _that_ platform, and they
wouldn't care whether they worked on PowerPC (we used an XDR version of
GNAT's stream attributes for communication between PowerPC and x86 with
no problems. But I have to say it was for recording for analysis rather
than for anything immediately mission-critical!)
