Me too. (When I remember correctly I never suggested to use this.)

I also think it this is much cleaner. What might look a little confusing 
now is that presence of the <name> feature alone turns normal in 
searched lib. (But this is not new.) <tag> alone (of course) is not 
sufficient. (<search> also will do of course.) Hmm, but <name> now looks 
a little bit redundant doesn't it?

Looks fine to me. (Altough I had no time yet to try it out.)

As you might see from my suggested patches:
1) I modified the types, so SEARCHED_LIB will not generate the lib 
prefix (which I think is wrong in the general case).

2) I modified the tag rule to take care for the lib prefix for windows only.
