Hi Richard and all,

    +# Ensure a consistent test environment by ignoring the system's Autoconf
    +# `configure` site defaults.
    +CONFIG_SITE=/dev/null; export CONFIG_SITE

I finally committed this change. Thanks for writing it up.

Hopefully Nelson (Beebe, who reported numerous failures with the 1.17.90
pretest) will have better luck with the next pretest. We'll see. 

Meanwhile, closing this one. --thanks, karl.
