You don't see my point. In autogen I want to have a way to select a
different shell (for configure & libtool). I'm not saying that I'll
choose a shell that fails to run the tools or that I'll not ask the
user for the best shell available...

Furthermore you seems to indicate that Dash would not run configure ?
 
Should autoconf find the correct sed program for example (@SED@), it
could also find the best shell available, isn't it ?

Sure. No comment.

Noted.
