Prepare to retire sys/dir.h in base.
Sorry I missed that one.
Question is it worth trying to fix it? I nuked it from the ports tree as it is an abandonware with no public distfiles. For other abandonware maintained by ports@ I have marked them as deprecated
https://svnweb.freebsd.org/ports?view=revision&revision=504002 removed from the port tree per https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=21519#c15
I will abandon this change later unless someone has objections.
