Is HAVE_TYPE_UNIONWAIT already being defined by configure?

This seems fairly odd -- are you sure it's right?  If we needed the
union wait, I would expect wait{pid}() to take the union type, not one
of its sub-types.

WIFEXITED is already defined (possibly with a different definition) on
most systems.  So it should at least be surrounded by "#ifndef
WIFEXITED".

WIFSTOPPED isn't used, so there's no reason to define it.  Or perhaps
you meant to define WIFSIGNALED?
