	GFC_UINTEGER_*, GFC_LOGICAL_*, GFC_REAL_*, GFC_COMPLEX_*. Update
	prototypes for gfc_itoa and xtoa.
	* io/io.h: Update prototypes for set_integer and max_value.
	* io/list_read.c (convert_integer): Use new
	GFC_(INTEGER|REAL)_LARGEST type.

	(next_char): Likewise.
	(read_decimal): Likewise.
	(read_radix): Likewise.
	(read_f): Likewise.
	* io/write.c (extract_int): Use new GFC_INTEGER_LARGEST type.
	(extract_real): Use new GFC_REAL_LARGEST type.
	(calculate_exp): Likewise.
	(calculate_G_format): Likewise.
	(output_float): Likewise. Use log10l for long double values.
	Add comment for sprintf format. Use GFC_REAL_LARGEST_FORMAT.
	(write_l): Use new GFC_INTEGER_LARGEST type.
	(write_float): Use new GFC_REAL_LARGEST type.
	(write_int): Remove useless special case for (len < 8).
	(write_decimal): Use GFC_INTEGER_LARGEST.
	(otoa): Use GFC_UINTEGER_LARGEST as argument.
	(btoa): Use GFC_UINTEGER_LARGEST as argument.
	* runtime/error.c (gfc_itoa): Use GFC_INTEGER_LARGEST as
	argument.
	(xtoa): Use GFC_UINTEGER_LARGEST as argument.
	* Makefile.am: Use mk-kinds-h.sh to generate header kinds.h
	with all Fortran kinds available.
	* configure.ac: Check for strtold and log10l.
	* Makefile.in: Regenerate.
	* aclocal.m4: Regenerate.
	* configure: Regenerate.
	* config.h.in: Regenerate.
	* mk-kinds-h.sh: Configuration script for available integer
	and real kinds.
	* lib/target-supports.exp: Add
	check_effective_target_fortran_large_real and
	check_effective_target_fortran_large_int to check for
	corresponding effective targets.
	* gfortran.dg/large_integer_kind_1.f90: New test.
	* gfortran.dg/large_real_kind_1.f90: New test.
