+// 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 have a problem.
+//
+// Solution: For 64-bit architectures, redefine NULL as 64-bit constant 0.

+// pointers to functions without specifying linkage unless you want to get
+// warnings.
+//
+// This also means that pointers to functions can no longer be "hidden"

+// point of view it causes a lot of warnings on old code using C header
+// files. Here are some typedefs to make the job of silencing warnings
+// a bit easier.
+//
+// The final kick in the teeth is that you can only have extern "C" linkage
+// specified at file scope. So these typedefs are here rather than in the
+// .hpp for the class (os:Solaris usually) that needs them.
