Hello, Lyncei,

The Bourne Shell "set" command may generate either of two different
output formats, POSIX, or non-POSIX.  cfg_defs.sh accounts for both
of these when generating config.cache.  Unfortunately these two cases
generate two distinctly different formats of config.cache.  Even more
unfortunately, cfg_defs.sh accommodates only the non-POSIX format.

Here's a patch.  Since I seem to be the entire POSIX user/developer
community, :-) there's no urgency to add this to 2.8.1.
