I'm not sure how the above works on meson - the define can come from
multiple places.
Surely meson does not check every header available on the system?

FWIW I've spent hours over the years looking at this ETIME workaround.
Due to $reasons various projects define the macro, some even without
checking if it's already set.
Memory is fuzzy, but I believe I've seen projects installing headers
with the redefine.

I sincerely hope that the FreeBSD devs can see waste of time this is
causing them and consider a more pragmatic solution.
