It isn't in many places, only 2 places in git-compat-util.h so far:

Too much? The 2nd part is not necessary NonStop specific, any idea for a
better way?

Well. NonStop is OK with it too.
And I've brackets with #ifdef _SC_OPEN_MAX, just like in compat/win23:

Well, I really have none but to disable that part:

It certainly is a workaround, whether it is clean or clean enough for now is
to you to decide ;-)
