Handle OpenBSD and NetBSD as FreeBSD / DragonFly are. OpenBSD would
need _XOPEN_SOURCE to be set to 700. Its simpler to just not set
_XOPEN_SOURCE.

I noticed this as well when testing your other fixes.
Just one question about this chunk:
> #define _DEFAULT_SOURCE 1
> -#define _NETBSD_SOURCE 1
Why remove this definition? I think it might be useful on some older
systems and seems harmless otherwise.
Other than that, I tested on OpenBSD 7.6 and NetBSD 10.0 and this patch
fixes the missing declarations. So:

Yes, it is curious.

_XOPEN_SOURCE restricts the build environment. _NETBSD_SOURCE is added
to counteract
_XOPEN_SOURCE. Not setting it in the first place provides everything by
default.
I was removing it as it should no longer be necessary.
But as said, it is harmless. I can leave it in if desired.

In Autoconf's AC_USE_SYSTEM_EXTENSIONS it is defined with the comment:
/* Enable general extensions on NetBSD.
Enable NetBSD compatibility extensions on Minix. */
I would prefer just leaving it for any old system that may need it. Or
in case git uses features from a recent standard that might still be
hidden as a NetBSD extension.
For example, POSIX.1-2024 has been released, but most functions added
there are still under _GNU_SOURCE in current glibc.
