no - I just realized what the problem was (there's no workaround for
what I _wanted_ to do, which was to show the actual default value in
the configure --help message, since that breaks quoting).
 
The problem (to recap - I'm seeing this less-late-at-night ;-)

#!/bin/sh -x
exec_prefix=/usr
libdir='${exec_prefix}/lib'
# this evaluates it
eval "echo $libdir"
# this doesn't
echo $libdir
# (in either case, I cannot put $libdir in a help-message & make sense out
# of it).

So what autoconf does is to avoid it altogether (that's where they use
the "EPREFIX" string in the help-message).

ok
