For the many people who picked up my patches to wu-ftpd-2.4 for NetBSD 1.0,
you should rush out and get the very latest wu-ftpd (wu-ftpd-2.4.2-beta13)
from wuarchive.wustl.edu (/packages/wuarchive-ftpd/).  It compiles right out
of the box on NetBSD 1.x ("./build nbs"), though you'll want to fix the last
two cases of using %ld printf strings for objects of type off_t (sigh...  I
just sent them mail about this, hopefully they'll fix it for beta 14 ;-).
They have conditional compilation cruft surrounding all the printf() calls
to use %qd; the following fixes cast the arguments to reply() calls to be
standard integral types (though it can, and probably should, use the %qd
cruft as well).
