Apparently GNAT uses it to indicate the "compilation system":
type Name is (SYSTEM_NAME_GNAT);
System_Name : constant Name := SYSTEM_NAME_GNAT;
So not very useful in our context either.
Apparently, it has no publicly available entity that would provide that information,
either, so a lot of projects simply do:
Is_Windows : constant Boolean :=
GNAT.OS_Lib.Directory_Separator := '\';
Does Janus/Ada have a similar directory_separator somewhere ? Seems like this kind of constant should be standard somewhere. Claiming Ada code is portable is nice (and
mostly true), but I believe almost all multi-platform projects end up with such a
requirement, in practice, if only to properly handle file names.
If thought Ada.Directories might help here, but apparently not.
