Where can I get "build"?

>From "The Fourth Generation Make", Glenn S. Fowler, in the proceedings of
the Summer 1985 USENIX:

	...However, the "build" variant of "make" introduced a major
	semantic change.  "Build" has "viewpaths" that allow source
	files to reside in more than one directory. ... The semantics
	of multiple directories, however, conflict with the flat, single
	directory approach of old-make ("old-make" refers to the "make"
	distributed with the System 5 UNIX system and "new-make" refers
	to the Fourth Generation "make"). ...

The Fourth Generation "make" *is* available from the AT&T Toolchest (or
whatever they call it), under the name of "nmake".  It is not, however,
compatible with "old-make", although there are, I believe, tools that
convert "old-make" Makefiles to "new-make" Makefiles.

If "build" is sold anywhere, it would probably be through the Toolchest;
contact your AT&T sales rep.  If it's a variant of "old-make", you'll need a
source license, probably an S5 license.  I don't know whether it is offered
or whether they consider "new-make" to have obsoleted it.
