The difference is that I don't want to step through the details
of implementation code.  The definition of getc() in stdio.h isn't
part of my source; it's part of the implementation.

Whether there is a real function named getc() or it is implemented
as a macro is an implementation decision that should not make a
difference in how I debug my source code.

(Obviously, if my intent was to debug stdio.h, then I would have
a different viewpoint.)
