 I don't understand why that code passes either WUNTRACED or
 WCONTINUED.  Why not just pass 0?

Note the patch Martin has posted is not needed, I've committed a change
to define WCONTINUED to 0 if not defined several days ago as obvious.

Adding Honza in the loop why he chose to use WUNTRACED | WCONTINUED.

The flag WCONTINUED for waitpid() is not portable.

The attached patch just defines it to 0 if missing.
