Fixed in CVS.  Thanks a lot!  Brown paper bag applied.

BTW: this particular piece of error/warning accumulator was lifted from
another package.  It is not an uncommon macro, so I suspect other packages
are broken in the same way.  It was latent with the older autoconf but the
switch to autoconf 2.50 made it surface: `config.cache' is now disabled by
default (because it tended to confuse new users) and must be switched on 
explicitly with `./configure -C'.

Ouch, this hurts
             -richy.
