I have tested this on a range of Darwin/macOS platforms and,
unfortunately, identified that I have ommitted one backport that
has considerable fallout on the latest macOS + latest Xcode.
The newer OS tools now emit a warning for the use of an
obsolete command line option - which leads to around 13k test
fails (e.g. https://gcc.gnu.org/pipermail/gcc-testresults/2025-July/852085.html)
The patch that’s needed is completely Darwin-local:
r14-2269-g3c776fdf1a8258
This affects Darwin23 (macOS 14/Sonoma) and later OS versions
that need the newer tools.
I wonder if it would be possible to apply this, since the branch will
now be closed and therefore there’s no opportunity to fix it in the
future.
thanks
