2007-01-16  Roger Sayle  <roger@eyesopen.com>

	PR fortran/30404
	* trans-stmt.c (forall_info): Remove pmask field.
	(gfc_trans_forall_loop): Remove NVAR argument, instead assume that

	Add an extra OUTER parameter, which specified the loop header in
	which to place mask index initializations.

	Change the semantics of MASK_FLAG to only control the mask in the
	innermost loop.
	(compute_overall_iter_number): Optimize the trivial case of a
	top-level loop having a constant number of iterations.  Update
	call to gfc_trans_nested_forall_loop.  Calculate the number of
	times the inner loop will be executed, not to size of the 
	iteration space.
