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 -

This one allows it to be used without #pragma (Microsoft specific I think) and when you click it takes you to the line since it shows the file and line number just like a regular err/warning message does since none of the other ones seem to do this. This used to work without the __pragma but newer versions of msvc require it. Ive been using it since sometime in the 90's. I use Visual Studio 2013

#define MacroStr(x)   #x
#define MacroStr2(x)  MacroStr(x)
#define Message(desc) __pragma(message(__FILE__ "(" MacroStr2(__LINE__) ") :" #desc))

example :

Message("Need to add unit testing here")

output: 1> c:\source\include\mithrilsoftware.h(180) :"Need to add unit testing here"
