A guess!  These are different constants that just happen to have the
same name!

The one in dirent.h is the size of buffer used (by the library) for its
sys_getdents() system call - and hence for the VOP_READDIR call.

The others are sizes used by filesystem code....

Does NetBSD manage to read directories from Windoze systems over NFS -
usng the MS supplied server (I've forgotten which Win-xxx it comes with,
probably 2k).  Another system I've used died horribly with buffer
overrun errors reading large directories from an NT system.....
