The same as on Windows.

That would not be necessary:
a) constref would be correct both for Windows and non-Windows
b) I'm not aware of a single routine that uses stdcall on non-Windows, other than the AddRef and ReleaseRef routines mentioned at the start of this discussion

If you want to apply a custom calling convention to an entire file, that is also already supported using {$calling xxx} (which I'm not very fond of either).
