Summary: Out of date make rationale about -n and $(MAKE)
Description:
Bug https://austingroupbugs.net/view.php?id=1436 added the requirement that
command lines which expand the
MAKE macro are still executed when -n is used, and removed some old
rationale about this feature, but missed some later rationale that should
also have been either removed or changed.
Desired Action:
Change:<blockquote>However, the System V convention of forcing command
execution with <b>-n</b> when the command line of a target contains either
of the strings "$(MAKE)" or "${MAKE}" has not been adopted. This
functionality appeared in early proposals, but the danger of this approach
was pointed out with the following example of a portion of a
makefile:<pre>subdir:
cd subdir; rm all_the_files; $(MAKE)</pre>The loss of the System V behavior
in this case is well-balanced by the safety afforded to other makefiles
that were not aware of this situation. In any event, the command line
<plus-sign> prefix can provide the desired
functionality.</blockquote>to:<blockquote>The System V convention of
forcing command execution with <b>-n</b> when the command line of a target
expands the <i>MAKE</i> macro was not adopted in earlier versions of this
standard, but it is now required because it has become widespread existing
practice.</blockquote>
