Correct.  My $ENV doesn't interfere in anyway - nor should any sanely
written one.  My point is that no build should rely on $ENV causing a
shell to do anything.  Now, because you & I have a sane $ENV script
does not mean everyone does.  One of the reasons I added the
MAKE_PRINT_VAR_ON_ERROR functionality was to help diagnose reported
build breaks.  Knowing that $ENV _cannot_ be a factor is handy.
