make(1) does not see environment variables

[Carl S. Gutekunst]

>On a Pyramid (5.0d 4.3BSD), makefiles can't seem to see env varaibles:

True. 4.3BSD make doesn't do that.

You can use the att (SVR3) make, which does read its variables from the envi-
ronment. (Of course, if you just use 'att make', your program will also be
compiled in the att universe.) The SVR3 make also has the -e option, which
causes variables from the environment to override the first assignment of
those variables in the makefile.
