Looking at Host/Target specific installation notes for GCC :
https://gcc.gnu.org/install/specific.html#older
There I see :
Starting with GCC 3.1, each release has a list of “obsoleted”
systems. Support for these systems is still present in that
release, but configure will fail unless the --enable-obsolete
option is given. Unless a maintainer steps forward, support for
these systems will be removed from the next release of GCC.
Really?
Where is that list?
gcc/config.gcc
# Obsolete configurations.
case ${target}${target_min} in
*-*-solaris2.11.[0-3]* \
| ia64*-*-* \
| nios2*-*-* \

if test "x$enable_obsolete" != xyes; then
echo "*** Configuration ${target}${target_min} is obsolete." >&2
echo "*** Specify --enable-obsolete to build it anyway." >&2
echo "*** Support will be REMOVED in the next major release of GCC," >&2
echo "*** unless a maintainer comes forward." >&2

Excellent! Thank you for the reply. This helps somewhat. I do trust
the above and question the "changes" below. I just did try to bootstrap
GCC 6.5.0 and did use the --enable-obsolete and then watched it fail in
stage1 regardless.
The changes are announced in the release notes for each releases, e.g.
https://gcc.gnu.org/gcc-14/changes.html (ia64 and nios2 declared obsolete)
https://gcc.gnu.org/gcc-13/changes.html (solaris 11.3 declared obsolete)
https://gcc.gnu.org/gcc-12/changes.html (cr16, 32-bit hppa-hpux, and
m32c declared obsolete).
etc.
OKay, this is helpful. However looking at :
https://gcc.gnu.org/gcc-6/changes.html
Where I see mention of "Solaris 12 is now fully supported." Ha. Ha.
Well, yes, this is archaeology but 2018 was not really very long ago
for the release of 6.5.0. I will dig around in gcc/config.gcc and see
what it says for release 5.x and even 7.x and others around the years
2014 or thereabouts.
Thank you very much for the good info.
