I didn’t, maybe debbugs did.

No, you don’t understand what I tried to write. The thing is, this
is about the *user* (the person calling the configure script) being
able to *override* the automatic mechanism to determine POSIX_SHELL
by setting CONFIG_SHELL to some value, forcing it to use it (if it
passes the tests).

Removing this ability will be A Bad Thing™.

I understand it extremely well.

>proposed patch affect your scenario? This is not about CONFIG_SHELL,

It is. Straight from your diff:

>  for gl_cv_posix_shell in \
>-"$CONFIG_SHELL" "$SHELL" /bin/sh /bin/bash /bin/ksh /bin/sh5 no; do
>+/bin/sh /bin/bash /bin/ksh /bin/sh5 "$CONFIG_SHELL" "$SHELL" no; do

This makes $CONFIG_SHELL no longer the preferred POSIX shell.

This breaks when a system has a /bin/sh that passes all gnulib
tests (and thus is used as POSIX_SHELL) but has other bugs that
make it unusable, for example. The user can then no longer over‐
ride this bad choice of the configury.
