include:
(1) Add a statvfs() implementation based on statfs(), and remove the
statfs() NetBSD-compatibility implementation. statvfs() is used
in src/usr.sbin/pkg_install on the HEAD branch.
(2) Add a fnmatch() implementation, needed by IRIX. fnmatch() is used
in src/usr.sbin/pkg_install on the HEAD branch.
(3) Remove fseeko(), inet_ntop(), inet_pton(), sl_*() strptime(), and
timegm() as they're not used by any of the bootstrap packages that
require libnbcompat (pax, mtree, pkg_install). All that's left is
what's necessary to bootstrap those three packages.
