Technically not, because the "struct foo" type remains incomplete until
you declare a complete type for "struct bar".  The easiest thing to do
is to have "foo.h" include "bar.h" right after the incomplete "struct foo"
declaration.  Then the application doesn't have to worry about it.

As you noticed, sometimes you can get away without doing it right.
