Correct. I didn't invent this path myself though; Florian Weimer did,
when he made the very first proposal for a standard ("GNU Ada
Environment Specification") back in 2001 or so.  IIRC, that
specification applied to the early .rpm packages for GNAT 3.13p
produced by the Ada for Linux Team.  So, it is possible that
/usr/share/ada/adainclude still exists in distributions other than
Debian.

Sorry about that :/ but as I've said many times, packaging is
difficult; if you want to concentrate on writing your software,
your best bet is to leave packaging to specialists of each target
platform while making their job as easy as possible.
