If I edit configure by hand to start

You shouldn't be writing configure tests that depend on Bash.
The whole point of autoconf is that it lets you test for features on a
system whose capabilities you do not yet fully understand. One of those
capabilities is exactly how functional the Bourne-style shell is. On
some systems, you won't find Bash *at all*, and on others, you will find
something that's crippled even by SysVR3 standards.
Your tests should cope with all of this, using only as much shell
functionality as is available on *all* of the systems you want to port to.
