Unfortunately this patch broke public-inbox on Darwin:
Bareword "SIZEOF_cmsghdr" not allowed while "strict subs" in use at /tmp/public-inbox/lib/PublicInbox/Syscall.pm line 456.
BEGIN not safe after errors--compilation aborted at /tmp/public-inbox/lib/PublicInbox/Syscall.pm line 460.
Compilation failed in require at /tmp/public-inbox/lib/PublicInbox/DS.pm line 31.

I’m not enough of a Perl person to fully untangle this. As
best I can tell, the intent is that non-Linux/BSD OSes should
still work with Inline::C, but this doesn’t work in practice
due to a bug?
It may also be possible to use the BSD approach on Darwin -
Darwin ascribes to the BSD school of thought where libc is the
only Officially Stable interface, but if you can get away with
it on the real BSDs maybe you can get away with it on fake BSD
too.
Best wishes,
Gaelan
