sounds useful!

you might be in luck with gcc-12 - it is clearly in development - but I
find it pretty stable (of course it might get very unstable) and another
caveat I'm on a x86_64 gnu/linux system most of the time.  I'm currently
building it slowly on a risc-v 64 bit machine and an older aarch64
debian stretch machine.

to avoid name C header filename clashes - for example system.h (and a few
others)

How does the m1 perform?
