* aclocal.m4 (gcc_AC_COMPILE_CHECK_SIZEOF, gcc_AC_C_CHAR_BIT,

	gcc_AC_C_LONG_LONG): New.
	* configure.in: Use them.  Probe the size of short, int, long,
	and long long/__int64 if we have them.  Move all the AC_C_*
	checks together, except gcc_AC_C_CHAR_BIT which has to go
	after AC_CHECK_HEADERS(limits.h).
	Take hwint.h out of host_xm_file and build_xm_file.

	* hwint.h: Unconditionally define HOST_BITS_PER_CHAR,
	HOST_BITS_PER_SHORT, HOST_BITS_PER_INT, HOST_BITS_PER_LONG,
	and HOST_BITS_PER_LONGLONG in terms of SIZEOF_* and CHAR_BIT.
	Move the HOST_WIDEST_INT setup logic here from system.h.
	Provide HOST_WIDEST_INT even if HOST_BITS_PER_LONGLONG is not
	defined.
	* system.h: Include hwint.h after limits.h.  HOST_WIDEST_INT
	is now handled by hwint.h.

	* config/alpha/xm-alpha-interix.h, config/alpha/xm-vms.h,
	config/c4x/xm-c4x.h, config/i370/xm-oe.h,
	config/ia64/xm-ia64.h: Don't define any of:
	HOST_BITS_PER_LONG, HOST_BITS_PER_CHAR, HOST_BITS_PER_SHORT,
	HOST_BITS_PER_LONGLONG.

	* config/alpha/xm-alpha.h, config/dsp16xx/xm-dsp16xx.h,
	config/h8300/xm-h8300.h, config/mips/iris6.h,
	config/mn10200/xm-mn10200.h, config/pa/xm-pa64hpux.h,
	config/sparc/xm-sp64.h: Delete.
	* config.gcc: Remove references to deleted files.

	* config/arm/xm-arm.h, config/mips/xm-mips.h: Don't define
	HOST_FLOAT_FORMAT to IEEE_FLOAT_FORMAT.
	* config/i370/xm-linux.h: Clarify floating-point situation in
	a comment.
