I could write some code in configure.ac to detect the current shell. But is
there any way to tell Autoconf to output a Bash shebang in the generated
'configure' script, instead of the standard "#! /bin/sh".
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.
