# a call to "configure". It had been used in an attempt to arrange that
# when one went "configure;make" the make step would not instantly
# invoke automake etc and then run the configure step all over again. But
# the test I had to do that were too bash-specific so I have backed off
# from that. The result will sometimes be configures that take a lot
# longer than is really necessary!
