fhopen() and flock(). This means that if you kill lockd, all locks will
be relased (but you're supposed to kill statd at the same time, so
remote hosts will know it and re-establish the lock).
Tested against solaris 2.7 and linux 2.2.14 clients.
Shared lock are not handled efficiently, they're serialised in lockd when they
could be granted.
and libs in the object tree, if you use a separate object tree,
while maintaining backward compatability with other build methods.
See the notes in src/share/mk/bsd.README for full details. Note
that the `make includes' target now only installs the include files
in the build directory (if you use one--otherwise they go in DESTDIR
just like before); `make install' will install include files in
DESTDIR.
