Hello,
[Perhaphs this has been addressed in a more recent make, my make is
pretty old...]
As far as I can tell, netbsd-make doesn't allow the path/name of the
sys.mk file to be changed (except by recompiling). Two questions
arise:
o should the user be allowed to do this?
(I want to so that I can use custom *.mk files).
o if so how?
Below is one possible method - checking the environment for a
MAKEDEFSYSMK variable.
