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 -

On Visual C++ you can just do

#pragma message(__FILE__ "(" _CRT_STRINGIZE(__LINE__) ")" ": warning: [blah]")

_CRT_STRINGIZE is often already defined in some header, but if it's not, you can define it:

#define _CRT_STRINGIZE_(x) #x
#define _CRT_STRINGIZE(x) _CRT_STRINGIZE_(x)
