RE: can't get shell var to work in rule

As Nestor points out, the "$l" in "$line" is expanded by make as the
variable "l", which is not defined and so expands to nothing.

Whenever shell scripting in make command scripts you _MUST_ remember to
escape all "$"'s you want passed to the shell.

  na> I had the same problem. Do the following:

  na> find $(TMPDIR) -name '*~' | while read line; do rm "$$line"; done

Note that this is not portable shell script syntax.  If you want to do
it portably you need:

  find $(TMPDIR) -name '*~' | (while read line; do rm "$$line"; done)
