David Morton asked

"He argues that the file foo.adb should be able to be compiled,
seperately, since the specification is there, even though the actual
procedure body has not been written.  I'm inclined to believe that he's right,
but gnat refuses to cleanly compile unless the file foo-bar.adb exists."

You can certainly compile foo.adb on its own, you must use the -gnatc switch
for this purpose, since code can only be generated if all subunits are
present. This is discussed in gnatinfo.txt.

Similarly the -gnatc switch can be used to compile subunits on their own.

(it's amazing all the things you can find in gnatinfo.txt)
