All these boil down to two different phrases, as words are
case-insensitive and the "." is a delimiter that splits off the
"in" which is dropped because it's too short (and a common

So the different phrases are "libu77 configure" and
"libu77/configure", and that difference is because the htdig
configuration says:
 extra_word_characters: _/
which as you might imagine, adds those two characters to the
characters that make up a search-word.

The underscore is there so you can search for variable names.
I did some archeology but I couldn't find why slash was added to
be considered part of a search word.  I've CC:ed overseers to
see if anyone remembers a valid reason.  If none can be found,
I'll remove the slash for the gcc side.  Thanks for reporting
