-// 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.
-//
-// Note: this fix doesn't work well on Linux because NULL will be overwritten
-// whenever a system header file is included. Linux handles NULL correctly
-// through a special type '__null'.

-// 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.
