Hm. I guess I was missing that part.

Is there a good reason to have an ancient autoconf for this purpose?
I could of course port the macros, but that would defeat part of the

Newer autoconf can properly compute fixed size types. This doesn't help
the various places that still require the BSD types.

strtoimax.c doesn't find _strtol.h otherwise. Other approach would be to
just move that to common as well, I wouldn't be surprised if that is
useful in kernel land later.

Lots of src/include (parts still used by toolchain) and e.g. libc still
depend on it. I agree that we should stop depending  on that, but it is
work. This is an intermediate step to just hack them up more cleanly.
