Re: Gnat 3.13p: Command_Name RM A.15

But at least you could take code developed on a Sun with GNAT and move
it to a PC with GNAT and account for the differences in how the two
platforms work. (File names, command line parameters, etc.) I've been in
this situation before and was very glad that GNAT worked so consistently
across both platforms. I may have had more trouble moving, say, from
GNAT/Unix to Aonix/PC, but that wasn't what I was doing. Having some way
to detect which platform I was on, may have helped me reduce the porting
issues even further.

Just because a thing isn't perfectly portable across all possible
compilers and platforms, doesn't mean it wouldn't be useful to have.
