  * Use intptr_t to avoid assumption that integers are 32 bit.
  
  Compiling wxHaskell on a 64bits platform fails, because there
  are some assumptions in the code that assume that integers are
  32bits. For example, there are a couple of assignments of a
  pointer to an int.
    
  This patch fixes these problems. Sometimes, after assigning a
  pointer to an integer, the int was used as a boolean value. In
  those cases, instead of returning a pointer p, I changed the
  code to return p != NULL. In two other cases, a pointer is stored
  inside the int and in these cases I changed the type of the
  int to intptr_t, of which it is guaranteed that a pointer can be
  assigned to it and recovered from it.
  
  Requires <inttypes.h>.

  * Added the -fPIC compiler flag to CXX options in the makefile.
  
  Apparantly, my platform (gentoo x86_64 linux) required that .o files are "relocatable" when there 
  are linked into a dynamic library.
  
  (It might be an idea to use libtool to hide this kind of platform-specific details)
