In my opinion, it should not do that.

I direct your attention to,
in which Robert Dewar asserts that "the sources at are
buildable with 3.13 or 3.14".  There has not been a release of GCC
with Ada as an official supported language since then.  Even when
there is, support for building with 3.13 or later has to be maintained
until the newer version is in wide use.  This is not negotiable.

[I would CONSIDER dropping support for 3.13 no earlier than when a
released stable version of Debian GNU/Linux provides an Ada-capable
3.x as the default compiler (i.e. not as "gcc-3.x").]
