Andrew,
fixed per https://github.com/OSGeo/gdal/pull/7660 . Your patch proposal
didn't work with older gcc versions that don't like the "::" in
_has_cpp_attribute(clang::fallthrough). I've reworked & simplified it.
I've verified it silences the warning with 23.04 + gcc 13
Even

Ubuntu 23-04 (Lunar) has g++ v13.0.1 (in the universe section,
this is not the default g++ compiler).
At least as curently shipped, this warns about the line
[[clang::fallthrough]];
(partly becuase with the default settings
[[fallthrough]];
is now needed to silence warnings where a fallthrough *is* intended).
Based on https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109653#c3
I have attached a patch for ports/cpl_port.h
Sorry, the previous patch did not mauch gdal's usage of CPL_FALLTHROUGH.
Please use this patch instead.
