You, the implementer, could manually replace that NAME_MAX with the
appropriate value (perhaps found by inspecting <limits.h>).  This is
the same issue as occurs when declaring v*printf() in <stdio.h>; the
related header need not (nay, MUST not) be included, but a compatible
type (or value in the NAME_MAX case) must be used.

What I did in my implementation was to cheat:
	char	d_name[1];
We were careful to word the IEEE Std 1003.1 specification so that
this is explicitly allowed.
