I will have to see if there is a way to only conditionally 'load' CancelIOEx so that cleanup can happen properly on vista and above but is not referenced at all under XP so that these programs keep working under XP.

Under Windows you could always (since Version 1.03, I think) link to a function using the GetProcAddress function. This is the classical way to link to DLLs at runtime instead of using the static pointers to DLL function contained in in library stubs in .LIB files.

MSDN gives the following example:

Code:


typedef void (WINAPI *PGNSI)(LPSYSTEM_INFO);

// Call GetNativeSystemInfo if supported or GetSystemInfo otherwise.

   PGNSI pGNSI;
   SYSTEM_INFO si;

   ZeroMemory(&si, sizeof(SYSTEM_INFO));
   
   pGNSI = (PGNSI) GetProcAddress(
      GetModuleHandle(TEXT("kernel32.dll")), 
      "GetNativeSystemInfo");
   if(NULL != pGNSI)
   {
      pGNSI(&si);
   }
   else 
   {
       GetSystemInfo(&si);
   }
