Another thing to think about is the C++ standard. It says that anything that can be implemented as a macro or function in the C standard should be implemented as the macro for C++. From section 17.4.1.2 paragraph 5: "Names which are defined as macros in C shall be defined as macros in the C++ Standard Library, even if C grants license for implementation as functions. [Note: the names defined as macros in C include the following: assert, errno, offsetof, setjmp, va_arg, va_end, and va_start. -end note] I'm not sure how well we comply with that.
