/**
 *	The next macros were introduced when TFORM was programmed. In the case of
 *	workers, each worker may need some private data. These can in principle be
 *	accessed by some posix calls but that is unnecessarily slow. The passing of
 *	a pointer to the complete data struct with private data will be much faster.
 *	And anyway, there would have to be a macro that either makes the posix call
 *	(TFORM) or doesn't (FORM). The solution by having macro's that either pass
 *	the pointer (TFORM) or don't pass it (FORM) is seen as the best solution.
 *
 *	In the declarations and the calling of the functions we have to use the
 *	PHEAD or the BHEAD macro, respectively, if the pointer is to be passed.
 *	These macro's contain the comma as well. Hence we need special macro's if
 *	there are no other arguments. These are called PHEAD0 and BHEAD0.
