Users also have the freedom of choice to move on (to some other 
software) when configure fails.

Bash is not always /bin/bash.  It may be installed in other paths.

The configure script does some checks of the current shell and it is 
not uncommon for it to decide to use bash rather than the initial 
shell.

Given your feelings about Autoconf's configure, perhaps you should use 
a configure look-alike as GNU lzip (written by Antonio Diaz Diaz) 
does.
