On almost all modern systems, a system call IS a call to some C subprogram. 
(On Windows, they're calls into a DLL; Linux appears similar although I've 
never studied the details.) There's nothing like the set-registers and trap 
like there was in the old days on MS-DOS, XENIX, and other systems.

So the only way to make a system call is via aspect Import to the needed C 
routine. (On Windows, I''d expect that a program that didn't do any system 
calls would be much smaller than a "normal" program; Windows needs some 
stuff added to every program; it doesn't have anything to do with Ada 
per-se.)
