This won't be clean, everyone is asking for something vaguely similar
but implemented in a completely different manner.

windows temp file support:
out.abs: $(objs)
$(LINK) $@ @<<
$(objs)
<<
====
With a Windows make program, the above snippet would write the contents of
$(objs),
one word per line, into a temp file and then invoke $(LINK) as
link out.abs @tempfilename
Note that it is the invoked executable that interprets the '@' character in
these
commands, not the DOS shell. This functionality is a holdover from the days
before
the DOS shell had real I/O redirection. (Although it's arguable whether it
really
does even now....) Unfortunately, even now that you *can* do redirection, I
don't
think most development tools will support it for this purpose.
While it should be simple enough to provide the functionality of dumping
variables
into temp files and providing their names, I don't see a single way to do it
that
will allow direct use of a Windows makefile, without tweaking/editing.
Basically,
this DOS version of Here Documents looks almost like the Unix version but is
different
enough to be hopelessly confusing.
I suppose for gmake you could rewrite the above as
out.abs: $(objs)
echo $(objs) > lnk.$$$$; $(LINK) $@ @lnk.$$$$ ; $(RM) lnk.$$$$

The snippet:
my_cfg_file :<
temp command line one
temp command line two
etc.
stage2: my_cfg_file stage1
my_exec -command my_cfg_file
(Copy temp command lines into my_cfg_file to make it, then use it in
stage2...) This
still looks like a job best left to echo. I suppose you could also use the
commandline
"printf" command as well, if you have it and are facing a quoting nightmare.
