That doesn't look like the standard fork problem, Ken.  The error comes
from semaphore::_fixup_after_fork:

  void
  semaphore::_fixup_after_fork ()
  {
    if (shared == PTHREAD_PROCESS_PRIVATE)
      {
	pthread_printf ("sem %p", this);
	/* FIXME: duplicate code here and in the constructor. */
	win32_obj_id = ::CreateSemaphore (&sec_none_nih, currentvalue,
						INT32_MAX, NULL);
	if (!win32_obj_id)
	  api_fatal ("failed to create new win32 semaphore, %E");
      }
  }

Error code 87 is ERROR_INVALID_PARAMETER.  The only two things that I
can see which would cause that problem are "sec_non_nih" and
currentvalue.

I'll change the error to report on currentvalue.  I assume that
currentvalue must be zero for some reason here and that is what is
causing the problem but it would be nice to know for sure.
