Re: Bug#746588: gnat should be an architecture dependent package
It is our policy to support the same version of gnat on all
architectures. The package gnat exists for this very purpose. Allowing
gnat to depend on different versions of gnat-x.y on different
architectures would defeat this purpose. If some architecture cannot
support the chosen version of gnat-x.y, then we prefer to drop support
for that achitecture altogether.
The transition from gnat-4.6 to gnat-4.9 has been planned and announced
in due course [3,4] (and furthermore accepted and approved by the Ada
maintainers), therefore should have come as no surprise to anyone
interested in Ada or gnat.
Therefore I am tempted to close this bug as WONTFIX. If you have
objections, please explain the benefits of making it easier to break
(Note that, pursuant to our policy, I intend to request removal of
gnat-4.8 in the near future.)
