in short -- how to get '\n' and '#' in (old) make actions
some fun
the following shell script works for some of the v7 makes and sunos4.0
$(sharp) expands to # and $(newline) expands to newline
you can then use $(newline) for actions with here documents and case statements
this is implementation dependent and non-portable since it takes advantage of
different cmd line vs. makefile assignment parsing

----- mymake ----
#!/bin/sh
/bin/make "$@" null='' sharp='$(null)#' newline='$(null)
'

----- here.mk -----
here :
	cat <<!$(newline)\
	$(sharp)hello world$(newline)\
	!

----- try it -----
$ omake -f here.mk
cat <<!\
 hello world\
!
cat: hello: No such file or directory
cat: world!: No such file or directory
*** Error code 1
make: Fatal error: Command failed for target `here'
$ omake -n -f here.mk null='' sharp='$(null)#' newline='$(null)
'
cat <<!
\
# hello world
\
!
# hello world
