That's correct. We cannot support command.com anyway :-)

That's not the autoconf's way. The autoconf's way is to find a better
shell on that system, e.g. /bin/sh5 or /bin/ksh. If it fails then it's Ok
for autoconf to fail.
But I still hope to work around those issues with QNX 4.25 somehow.
How about this:
ac_output=`command || echo "===ERROR==="`
case $ac_output in
*===ERROR===)
AC_MSG_ERROR([command failed]) ;;
*) ;;
esac
