// 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.

// ANSI C++ fixes
// NOTE:In the ANSI committee's continuing attempt to make each version
// of C++ incompatible with the previous version, you can no longer cast
// pointers to functions without specifying linkage unless you want to get
// warnings.
//
// This also means that pointers to functions can no longer be "hidden"
// in opaque types like void * because at the invokation point warnings
// will be generated. While this makes perfect sense from a type safety
// 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.
