Yes, there is a benefit. To be able to locate _WHERE_ you installed the 
files (location of headers and location of the libraries).

Well, first of all you are telling me "no, you can't answer my question" 
yet you say "you don't need to know". That is contradictory to me.

You are incorrectly making the assumption that if it is not in the path I 
will "bomb out" of configure (which is what the macros will do).

But I do not wish to do this. I wish to conditionally compile Ogg Vorbis 
support (#ifdef HAVE_VORBIS).
