That makes a lot of sense to do on Unix-alikes, but less so on Windows. 
  A local repository of tarballs needs to be in src/contrib below the 
URL of the repository.  On Unix setting that up as a soft link to the 
real location would be trivial, but on Windows you'd probably want that 
to be the only path to the files, and that's not very convenient when 
you're already used to keeping them elsewhere.
