:Well, quickworld seems easy to implement on FreeBSD (maybe I should
:have more docs in Makefile.inc1). Sorting in TGTS could be better in
:this patch too. Maybe quickworld target itself should go somewhere
:else. realquickworld appears, from your description, to be
:'everything' in the FreeBSD 5.

:Anyway, the following patch appears to work for me.

Looks pretty good. Our's also runs _obj (before _includes), because it
is quite common for a developer to commit new code that requires a new
object directory. My conclusion was that the saved time wasn't worth
the possibility of a buildworld either failing due to the lack of an obj
directory for a new module, or improperly creating the objects for the
new code in the source tree because no obj directory exists (if the
source tree is R+W).
I think you will find it a very useful target. I use it all the
time and just do a full buildworld on the occassion when quickworld
fails. Our developers also know that if quickworld fails they should
do a buildworld and we rarely get postings to bugs@ about it.

In dfly it is:
quickworld: _obj _includes _libraries _depend everything
In dfly the realquickworld is as shown below. Not quite just
'everything'. _includes and _libraries are probably not necessary but
I recommend that the _obj target always be run to avoid accidental
/usr/src pollution.
realquickworld: _obj _includes _libraries everything
