Re: Bug#746588: gnat should be an architecture dependent package

There are two transition periods.  The first one started on 2014-02-03
with the announcement of gnat-4.9 and ended on 2014-05-01 with the
upload of gnat (=4.9).  This three-month period was to bootstrap and
stabilize gnat-4.9.  The second transition period started with the
upload of gnat (=4.9) and is for the upgrade and recompilation of all
Ada packages.  This second period ends with the freeze (2014-11-05) and
we really need all the time we can get.  In fact, right now I should be
spending my time on libgtkada or some other package.

If I had been aware of your porting efforts, I might have delayed the
upload of gnat (=4.9) by a few days but not weeks.

The problem is simply that m68k failed to produce a working gnat-4.9 in
time for the upload of gnat.  As I said, if I had been aware of your
efforts I could have helped a little.

Yes, really.  I'm not saying this to disparage your work or your
dedication but, honestly, how many people do you think write and deploy
Ada programs, on Debian, on m68k machines?  Ada is a minority language,
for starters.  popcon shows ~1000 installs of gnat-4.6 on all
architectures of Debian (compare this with ~170k installs of libc6).  In
my 10+ years of maintaining Ada on Debian, I have learned to allocate my
time in the way that I perceive will benefit the most users.  Sorry.

What I can do for you at this point is accept your m68k patches and
apply them in future uploads of gnat-4.9.

No, the Debian Ada Policy says that packages must build-depend on both
gnat and gnat-4.9 (and explains why).
