OK to push (after more testing) the attached
'Revert parts of "[Ada] Reduce runtime dependencies on stage1"', for the
reason detailed therein? Should the comment before 'GNAT1_C_OBJS' be
re-instated/adjusted, too? Would appreciate a careful review, as I don't
really know what I'm doing there. ;-)

Unfortunately it's not OK, these are the most annoying/delicate dependencies, so
we'd rather not reintroduce them. I'll instead update prerequisites to
document that GCC 5.1 or later is required to build GNAT.
Sorry for the inconvenience!

Hi!
(Before the GCC 12 release) I had reported that commit
r12-6398-ga6eae6a9bbf83ada3aab7f5a2a74e7024889d237
"[Ada] Reduce runtime dependencies on stage1" has broken GCC/Ada build
with GCC 4.8. That's unfortunate, as I understand that GCC 4.8 is
generally the prerequisite compiler for GCC. (..., and I like to do
certain build using that old version, to make sure that this still
works.) (The issue later also got repoted by Bernd Edlinger in
<https://gcc.gnu.org/PR104710> "Ada-Bootstrap fails with gcc-4.8.4".)
I thus had suggested a patch to
'Revert parts of "[Ada] Reduce runtime dependencies on stage1"', but:

"[Ada] Implement AI12-0187 (Stable properties of abstract data types)".
So, what is actually the prerequisite GCC/Ada compiler version to be able
to build GCC 12+ GCC/Ada?

Ah, that's unfortunate. I guess on my side I'm using a version of GNAT built
without assertions, so not failing on this.

I'm afraid I don't have more info at this stage, I assume GCC 6.1 would work
(not tested, if someone could confirm that would be great).
