How can I use #pragma message() so that the message points to the file(lineno)?

Question

In order to add \'todo\' items into my code, I want to put a message in the compiler output.
I would like it to look like this:

c:/temp/main.cpp(104): TODO -

Use the # token. I've posted an example from MSDN below:

// collisions.h
#define __STR2__(x) #x
#define __STR1__(x) __STR2__(x)
#define __LOC__ __FILE__ "("__STR1__(__LINE__)") : Warning Msg: "

// collisions.cpp
#pragma message(__LOC__"Need to do 3D collision testing")
