So I've been tracing the execution of "configure", but I don't CONFIG_SHELL
to be set, and the script reaches a point that the following happens:
SHELL=${CONFIG_SHELL-/bin/sh}
export SHELL
So SHELL is now /bin/sh and config.status is generated as such:
It now occurs to me to ask exactly which version of Autoconf generated
this configure script.
At the top of configure:
#! /bin/sh
# Guess values for system-dependent variables and create Makefiles.
# Generated by GNU Autoconf 2.69 for hello 1.0.
There *should* be code immediately above the
SHELL=${CONFIG_SHELL-/bin/sh} line that *should* have detected that
/usr/xpg4/bin/sh is the right shell to use on this system. It's
possible that its tests are not stringent enough. Do you see a
variable named "as_required" being set in your logs, before this
point? If so, please tell us what it's being set to. If not, please
tell us it's not there.
