Get filename and line number in pragma message

Ever wanted to get proper "double clickable" file name and line number output from your #pragma message() statements?

Use the following defines (for example in stdafx.h):

#define __STR2__(x) #x
#define __STR1__(x) __STR2__(x)
#define __LOC__ __FILE__ "("__STR1__(__LINE__)") : "

Then use __LOC__ in your #pragma message() statements:

#pragma message(__LOC__"This code will be completed in Phase 2")

At which point you should see the following compiler output:

C:\honda\2.5g\PC\runtime\SILinkProcess\SiLink_helpers.cpp(567) : This code will be completed in Phase 2

Very handy!
