Every OS is different in how it builds executables and links to 
libraries. DOS is different to Windows and Unix. VMS is different again. 
IBM OS/390 is different again. And other OS like Vxworks, and OS/9 are 
similar to *nix but not quite the same. You are really
in the depths of OS internals and need to research every platform on its 
own merits.

The good news is that all unix variants (including Solaris,
BSD, Darwin(MacOS) and linux work very similarly) And Windows is the 
only mainstream exception, at least on the desktop. So unless you are 
writing server software its not too bad.
