| Consider what happens if you write:
| When DPRINTF() expands 'if (xxx) yyy' it all goes horribly wrong.
Of course, the do { } while(0) wrapping is needed in the DPRINTF
expansion - that was also added - that's there to deal with problems
just like that. WIth that, DPRINTF() acts just like a function
(except it has no value of course) for syntax purposes, and doesn't
need to be surrounded with {} every time it is used.
