Of all the problems I've had using PHP on 64-bit platforms (e.g. bug
#21973, which refers mainly to lib directory naming under commercial
64-bit environments), this was not one of them -- yay.

So I am curious:
 - What is the purpose of having the mechanism to remove or not remove
   /usr/lib (and why not do the same for /lib and other vendor
   directories)?
 - Why do 64-bit Linux operating systems need the special hard-coded
   treatment?
 - Will the same be done for other operating systems?
