Well, an easy situation would be if the shell is bash; it's builtin echo
has a -E option to do just that (i.e. not expand anything).  I had to
use that option in a few changes I made for the DJGPP package, as
autoconf would otherwise seriously mess up DOS-style paths.
Not sure if other incarnations of echo are so friendly as to provide
such a option though.
