+// 4810578: varargs unsafe on 32-bit integer/64-bit pointer architectures
+// When __cplusplus is defined, NULL is defined as 0 (32-bit constant) in
+// system header files.  On 32-bit architectures, there is no problem.
+// On 64-bit architectures, defining NULL as a 32-bit constant can cause
+// problems with varargs functions: C++ integral promotion rules say for
+// varargs, we pass the argument 0 as an int.  So, if NULL was passed to a
+// varargs function it will remain 32-bits.  Depending on the calling
+// convention of the machine, if the argument is passed on the stack then
+// only 32-bits of the "NULL" pointer may be initialized to zero.  The
+// other 32-bits will be garbage.  If the varargs function is expecting a
+// pointer when it extracts the argument, then we may have a problem.
+//
+// Solution: For 64-bit architectures, redefine NULL as 64-bit constant 0.
+#ifdef _LP64

+// 64-bit Windows uses a P64 data model (not LP64, although we define _LP64)
