	.1.ada and .2.ada is the variant I've seen most often outside of
.ads/.adb. It's even a built-in alternative for GPS.

	Even the Ada83 cross-compiler I'd had to use on my last employment
seemed to be configured to the GNAT .ads/.adb convention (along with a few
other extensions for processor specific code -- apparently how they handled
the equivalent of dual code trees; one for target, one for simulation
system). Granted, this may have been a result of some historical
refactoring so they could use GNAT on Windows for test compilation/editing,
as telnet into a VMS box (virtual for the last half decade or so) is not
comfortable -- VMS editors don't translate well to non-VT keyboards.
