Seems straightforward to me, at least in this case...

This is right, of course.

  cz> address@hidden:~/mk$ uname
  cz> IRIX64
  cz> address@hidden:~/mk$ echo $HOME
  cz> /home/ess/zender/zender
  cz> address@hidden:~/mk$ make -f Makefile.tst
  cz> HOME = /home/ess/zender/zender

This is "wrong", of course.

I don't have an Irix system nor have I received any reports like this.

It looks to me like the Irix version thinks you have the make -e
command-line option set.  Are you sure you haven't set MAKEFLAGS to -e
in your Irix login environment or something similar to that?
