Correct.

Basically, GCC 4.x was an absolute mess in changing command line
options and behaviours (cetainly on the ARM* side, but I think also
for x86). Since GCC 5.0, this has stabilised a lot, so we
haven't needed to produce any version-specific profiles since that one.

GCC9 looks "interesting" in throwing up new buildtime warnings (from
looking at other projects), so it might be that it will need a new
profile, but it may also be that all those are genuine bugs and need
to be fixed.

Certainly, any issues people come across, please report.

Leif
