That's pretty cool! :-)

Usually that means that either ECHO is screwed up and the reexec ends up
sending configure to stdout rather than doing fallback echo, or else 
there could be a bug in one of the $0 expansions getting done wrong, or
maybe a sed command is doing the wrong thing.

Yes, because you could use it to lt_dlopen with the preloading linker.
