Silly me. You're right. The weird thing is that I've used Unchecked_Access  
with GNAT (interfacing to Windows). I guess GNAT just allows it. Or was it  
Unchecked_Address? My memory is not very good. I'm very sorry for any  
confusion caused.

I think compilers should provide a non-standard mode permitting  
Unchecked_Access for subprograms, since it's obviously needed sometimes;  
this mode would be forbidden for safety-critical software.
