`#pragma message("foo")` results in the following output:

foo

and shows nothing in the IDE warning list. So you either don't see it, or if 
you do, you have no clue where did it come from.

`#warning foo` would result in the following output:

source_file(source_line): warning C7563: #warning foo

which would then be shown as a warning in the IDE.
