If you decrease MAXNAMLEN you *must* version! Anyway we came from there,
and there is no reason to move backwards. The change proposed is to make
NAME_MAX match MAXNAMLEN without bumping.
Yup, I forgot about getdents(2) compat.
BTW, why would it be necessary to version? d_name is the last element of
struct dirent; I can't see how d_name content could be bigger than 256
(including NULL) anyway, so only those that copy d_name string with
MAXNAMLEN size directly (instead of using _PC_NAME_MAX, NAME_MAX or
strlen(3)) are in trouble, no?
