Indeed.  I was trying to see whether libtool's fallback echo (where it calls 
itself recursively and writes out its arguments as a here document) would do 
the right thing.

The problem is that libtool.m4 jumps through a bunch if hoops to find an echo 
that doesn't interpret backslashes, since it is quite a common problem, which 
causes libtool a lot of headaches.  While jumping through these hoops it 
should notice that zsh's echo doesn't have the properties that libtool needs 
and keep trying, finally using `libtool --fallback-echo' as its echo command 
if it cannot find a builtin or a binary that works.

Does zsh have a `printf' builtin?  Maybe that will work -- it is what we use 
for ksh.

Anyway, I have temporarily changed the backticks for darwin to $() until we 
have time to solve this correctly.

Cheers,
        Gary.
