Not needed; the following sequence removes trailing whitespace in Emacs: ESC-x picture-mode NL CTL-c CTL-c (picture-mode cleans up trailing whitespace on exit). The problem, though, is the program behavior is affected by something that is invisible (the trailing whitespace). If it's an issue that different compilers handle this differently and that the standard does not specify the behavior, the answer, I think, is to warn when trailing whitespace affects the behavior of the program. I think that the only case is when the last character is a \ but there may be others.
