to override @-prefixed commands in Makefiles. It is especially useful for
debugging ports and/or complex Makefiles in such a manner that is basically
a last resort, but is quite effective if the output is well-handled.
I'll update the manpage after dinner. ;-)

says it pretends to make.
This bug was apparently harmless except for normal cases involving
.ORDER statements when it made debugging of -jN using -n very
confusing. E.g., for:
.ORDER: beforedepend .depend
depend: beforedepend .depend
where beforedepend depends on something so that it is not initially
up to date, `make [-n] -j2 depend' causes `make' to wait for itself
to make beforedepend. This works fine without -n. The job to make
beforedepend has normally been started, and beforedepend is marked
as made when the job completes. However, with -n, the pseudo-job
for making beforedepend has normally completed, and in any case
there was no chance of beforedepend being marked as made. `make'
actually exited almost immediately with status 0 instead of waiting
forever.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
- Add the .PHONY, .PARALLEL, and .WAIT directives
- Added the -B and -m commandline flags
- misc. man page cleanups
- numerous job-related enhancements
- removed unused header file (bit.h)
- add util.c for functions not found in other envs.
- and a few coordinated whitespace changes

problems in the process:
1. Quoting should work properly now. In particular, Chet's reported bash
make problem has gone away.
2. A lot of memory that just wasn't being free'd after use is now freed.
This should cause make to take up a LOT less memory when dealing with
archive targets.
3. Give proper credit to Adam de Boor in a number of files.
