Sorry, I used the wrong words. I didn't really mean "conforming" as 
"conforming C implementation".

What I really meant was that with that macro you could perform the cast 
on the pointer returned from malloc only when compiling as C++, and 
avoid the cast in C, in order to "conform" to C best practices [1] that 
advice against casting that pointer (as opposed as what you should do in 
C++), as Sean said.
