	PR libfortran/32731
	* iresolve.c(gfc_resolve_pack):  A scalar mask has
	to be kind=4, an array mask with kind<4 is converted
	to gfc_default_logical_kind automatically.
	(gfc_resolve_unpack):  Convert mask to gfc_default_lotical_kind
	if it has a kind<4.

2007-07-14  Thomas Koenig  <tkoenig@gcc.gnu.org>

	PR libfortran/32731
	* gfortran.dg/pack_mask_1.f90:  New test.
	* gfortran.dg/unpack_mask_1.f90:  New test.
