Good point, but please recall what I've already said. I still can't
upgrade to testing because I can't rebuild gcc-defaults_1.81 -- it
requires rebuilding gcc-4.3_4.3.3-3, gcj-4.3_4.3.3-3, and
gnat-4.3_4.3.3-2. gcj-4.3 FTBFSed first, then I discovered that gcc-4.3
FTBFSes too; then I've found upstream requirement of autoconf_2.59, and
that there's gcc-4.3_4.3.3-7 (those days) in unstable, what can't
migrate. I've attempted 7th revision and it succeeded. Than I've found
#523509, contributed to it (I would like to think that my contribution
had some value), and then gcj-4.3_4.3.3-8 succeeded too.
Let's back to gnat-4.3_4.3.3-2 for now.

*SKIP*
(please don't consider me ranting, just for clarity) A long time ago I
had sex (let's call that process what it was) upgrading BlackCatLinux
6.1 (RHL-6.0 in background) to RHL-7.3 Slackware-way. So I have some
minor understanding what "./configure-make-make_install" charm is.

Thus that clear (and hopefully useful for someone else) explanation
motivated me to recall old practicies. That's what I've found.
Since I build with pdebuild-internal, C-hook isn't an option for me.
I've --login'ed, and installed gnat-4.3 . It pulled obvious
dependencies, except gnat (because gnat is the reverese depends).
${CC} -c conftest.adb
That ${CC} I've decoded as 'gnatgcc' from 247line of config.log
ac_cv_prog_CC=gnatgcc
Attempt to run
gnatgcc -c conftest.adb
then obviously fail because gnatgcc is missing. It's in gnat package,
that's uninstalled. Attempt to install plain gnat fails, because
gnat: Depends: gnat-4.3 (>= 4.3.3-2) but 4.3.2-1 is to be installed
Then after installing gnat_4.3.2-2 (I don't understand from where that
4.3.2-1 was pulled) compiling that conftest.adb thingy succeedes. Then
I've checked if installed dependecies happen to be the same as while
build fails.
Then I've found that gcc-4.3_4.3.2-1.1 is installed. I've upgraded it
to gcc-4.3_4.3.3-7, and...
fatal error, run-time library not installed correctly
cannot locate file system.ads
compilation abandoned
Obviously none could complain that gnat_4.3.2 fails with gcc_4.3.3. Why
they don't conflict each other is another issue going beyond the scope
of this bugreport... Or gnat_4.3.2 should work with gcc_4.3.2 and
nothing else...
And everything that doesn't matter. I've tried to preinstall gcc-4.3
and gcc-defaults binaries -- for unknown reason gcc-4.3 happened always
to be upgraded up to version 4.3.3-7.
And the reason is this: gnat-4.3 build-depends on gcc-4.3-source.
And that gcc-4.3-source_4.3.3-7 depends on gcc-4.3-base (>= 4.3.3-1).
Fin. I think none would be able to build gnat-4.3_4.3.3 off
gcc-4.3-source_4.3.2. Is there a way to make gnat-4.3_4.3.2 to work
with gcc-4.3_4.3.3? Is there a way to make gcc-4.3_4.3.3 and
gcc-4.3_4.3.2 coexist? All that is done by tweaking debian/control
behind the scene? What I have to pull off mirror of gnat-4.3_4.3.3
packages to build gnat-4.3_4.3.3?
So my request is still in effect -- is it possible to apply the black
magic already applied on gcc-4.3 and gcj-4.3 on gnat-4.3 too? Please,
that's the only hope.
