Below is a small patch for the IUBio version of Wais release 8 beta 5,
which includes Booleans, partial words, and literals.  This patch fixes
the "not not" bug, failure when two or more of the boolean NOT operators
are used in a query.

Note: If you use the gopher server gopherd with IUBio WAIS linked in, you will
need to relink the gopherd program.

The full version of IUBio-modified WAIS can be picked up by ftp/gopher to
ftp.bio.indiana.edu, in folder IUBio-Software+Data/util/wais as 
iubio-wais-8b5-c.tar.Z
