	unpack_r16.c, unpack_c4.c, unpack_c8.c, unpack_c10.c
	and unpack_c16.c
	Add i_unpack_c to gfor_built_src.
	Add rule to generate i_unpack_c from m4/unpack.m4.
	* Makefile.in:  Regenerated.
	* libgfortran.h: Add prototypes for unpack0_i1, unpack0_i2,
	unpack0_i4, unpack0_i8, unpack0_i16, unpack0_r4, unpack0_r8,
	unpack0_r10, unpack0_r16, unpack0_c4, unpack0_c8, unpack0_c10,
	unpack0_c16, unpack1_i1, unpack1_i2, unpack1_i4, unpack1_i8,

	unpack1_c4, unpack1_c8, unpack1_c10 and unpack1_c16.
	* intrinsics/pack_generic.c (unpack1):  Add calls to specific
	unpack1 functions.
	(unpack0):  Add calls to specific unpack0 functions.
	* m4/unpack.m4:  New file.
	* generated/unpack_i1.c:  New file.
	* generated/unpack_i2.c:  New file.
