Clean written code should not care about pointers or integers are 32 or
64 bit or byte order. Code written in a higher language should run on
any hardware, otherwise I call it "defect".

And concerning the memory usage: don't forget, mixing 32/64 bit shared
libraries doubles the memory needs. Sharing of libraries only makes
sense if they are really shared, otherwise you can link programs static.
BTW: That's an illness on windows, where every application brings it's
own "shared" library version x.y, that never becomes really shared.
