What you want are the two typedefs intptr_t and uintptr_t . Each one is defined to be an integer big enough to hold a pointer (the former being signed, and the latter being unsigned); they aren't mandatory, though, so you might have

  #if defined(__COMPILER1__) || defined(__COMPILER2__)
    typedef intptr_t fixnum;
  #else
    typedef long fixnum;
  #endif
This would guarantee you correct behaviour if intptr_t were defined, and probably give you the correct behaviour even if it weren't.

From this?

  #include<stdint.h>
Hmm. Interesting. How well supported is it?
