"make" is not native to TOPS-20, and is unknown to the vast majority of TOPS-20
programmers.  The best thing to do is to get the source for make and run it
under DDT to see where it's failing to perform as you expect, and fix it yourself.

It is unfortunate that Unix make was ever ported to TOPS-20, because there was
already a MAKE command which invoked TECO with an empty buffer.  This is the
source of the joke response to "MAKE LOVE"; it has nothing to do with your
issue with the Unix program.

Instead of using a badly ported Unix program, you ought to learn to build
TOPS-20 control files and do your compiles that way.

Just my $0.02.
