I don't think that (quoting Pixie sources which you probably refer here) in
simple #if #else:

    #ifdef WIN32
	// Win32 stuff here
	cModule	=	LoadLibrary(name);
    #else
	// Unix stuff here
	cModule =	dlopen(name,RTLD_NOW);

all the platforms are handled. Even in wxWidgets where we wrap C++ around native
APIs (http://www.wxwidgets.org/manuals/2.5.3/wx_wxdynamiclibrary.html), we have
5 different representations of wxDllType and still do not cover all the possible
cases:

  // Note: WXPM/EMX has to be tested first, since we want to use
  // native version, even if configure detected presence of DLOPEN.
  #if defined(__WXPM__) || defined(__EMX__) || defined(__WINDOWS__)
    typedef HMODULE             wxDllType;
  #elif defined(HAVE_DLOPEN)
    #include <dlfcn.h>
    typedef void               *wxDllType;
  #elif defined(HAVE_SHL_LOAD)
    #include <dl.h>
    typedef shl_t               wxDllType;
  #elif defined(__DARWIN__)
    typedef void               *wxDllType;
  #elif defined(__WXMAC__)
    #include <CodeFragments.h>
    typedef CFragConnectionID   wxDllType;
  #else
    #error "Dynamic Loading classes can't be compiled on this platform, sorry."
  #endif
