	* expr.h (default_init_builtins): Delete prototype.
	* doc/tm.texi: Document TARGET_INIT_LIBFUNCS and US_SOFTWARE_GOFAST.
	Tweak documentation of TARGET_FLOAT_LIB_COMPARE_RETURNS_BOOL.
	Remove documentation of INIT_TARGET_OPTABS, MULSI3_LIBCALL,
	DIVSI3_LIBCALL, UDIVSI3_LIBCALL, MODSI3_LIBCALL, UMODSI3_LIBCALL,

	* config.gcc: Remove all references to pa/long_double.h,
	ia64/hpux_longdouble.h, and gofast.h.
	(mips-*-*): When --enable-gofast, just add US_SOFTWARE_GOFAST
	to tm_defines; don't set INIT_SUBTARGET_OPTABS or change tm_file.

	* config/alpha/alpha.c, config/c4x/c4x.c, config/cris/cris.c
	* config/frv/frv.c, config/h8300/h8300.c, config/i860/i860.c

	* config/sparc/sparc.c, config/vax/vax.c:
	Provide a definition for TARGET_INIT_LIBFUNCS.  Where
	necessary, include optabs.h, libfuncs.h, and/or config/gofast.h.

	* config/sparc/sparc.h, config/v850/v850.h, config/vax/vax.h
	* config/vax/elf.h: Don't define or use INIT_TARGET_OPTABS,
	INIT_SUBTARGET_OPTABS, or any *_LIBCALL macros.

	* config/ia64/hpux.h: Redefine INTEL_EXTENDED_IEEE_FORMAT to 0.
	Set TARGET_INIT_LIBFUNCS and FLOAT_LIB_COMPARE_RETURNS_BOOL here.
	* config/pa/pa-hpux.h: Define LONG_DOUBLE_TYPE_SIZE,
	HPUX_LONG_DOUBLE_LIBRARY, and FLOAT_LIB_COMPARE_RETURNS_BOOL here.

	* config/sparc/sol2.h: Redefine SUN_CONVERSION_LIBFUNCS and
	SUN_INTEGER_MULTIPLY_64 to 1.
	* config/sparc/elf.h: Redefine SUN_CONVERSION_LIBFUNCS and
	SUN_INTEGER_MULTIPLY_64 to 0.
	* config/sparc/lite.h, config/sparc/liteelf.h, config/sparc/sp86x-elf.h:
	Define US_SOFTWARE_GOFAST.
	* config/vax/vax.h: Default TARGET_ELF to 0.
	* config/vax/elf.h: Redefine TARGET_ELF to 1.

	* config/gofast.h: Don't define any macros here.  Provide one
	static function, gofast_maybe_init_libfuncs, which does what
	INIT_GOFAST_LIBFUNCS used to do but only if US_SOFTWARE_GOFAST
	is already defined.  Do not clear negation libfuncs.  Do
	not mess with HFmode, XFmode, or TFmode libfuncs.

	* config/avr/avr.c (avr_init_once): #if 0 out; mark FIXME.
