64bit why can't you just compile 32bit apps into 64bit

The only changes that I know right now between 64bit and 32bit is the length on an int and long. Can someone please explain to me why they can't just re-compile the code as 64bit?

Who's 'they'?

Lots of code implicitly assumes within the code itself that pointers are a certain size. The code that's relatively better written and doesn't assume things like that works just fine with a recompile. You can't recompile Skype, though, since there's no source code available.
