Consider what happens if you write:

When DPRINTF() expands 'if (xxx) yyy' it all goes horribly wrong.
That's why I changed it to
do { if (xxx) yyy; } while (0)
a week or two ago. (That change was not pulled up to netbsd-7,
although other changes made around the same time were pulled up.)
Do we need to support any compilers that don't support __VA_ARGS__ ?
Even microsoft's compiler almost supports it.
I don't know.
