I don't know about the utility of example scripts in general, but for
this specific case, I strongly feel autoconf should automatically
detect this and reexec the configure script under /bin/ksh.
If we follow "Freeman's Rule" then even the example script can be
misunderstood and having autoconf find ksh for you and run it behind
the scenes would be safer IMHO.
E.g. stick something like this near the top of every configure.ac in
the gcc tree:
if test -z "$REEXECED" ; then
if test -z "$CONFIG_SHELL" ; then
CONFIG_SHELL=/bin/ksh ; export CONFIG_SHELL
fi
REEXECED=1 ; export REEXECED
exec $CONFIG_SHELL $0 $@
fi
It's untested so you may need to tweek it. But it conveys my idea.
