Okay, I've tried that, and I'm kind of puzzled to report that it
doesn't seem to work correctly with bash (invoked either as bash or as
sh), failing like this:

% bash ./configure
configure: creating ./config.status
config.status: creating Makefile
./config.status: line 697: unexpected EOF while looking for matching ``'
./config.status: line 714: syntax error: unexpected end of file

but (and this is the *really* strange part) it runs to completion with dash!
