Update.

1998-06-27  7:07  Richard Henderson  <rth@cygnus.com>

	* math/atest-exp.c (exp_mpn, main): Cast to mp_limb_t appropriately.
	* math/atest-exp2.c (exp_mpn, main): Likewise.
	* math/atest-sincos.c (main): Likewise.

	* resolv/inet_addr.c (inet_aton): Check for 32-bit overflow.  Move
	base handling away from strtoul.  Always reset errno.

	* sysdeps/alpha/Makefile (elf): Kill -mno-fp-regs.

	* sysdeps/alpha/dl-machine.h (elf_machine_runtime_setup): Only set
	_dl_profile_map if _dl_name_match_p.
	(RTLD_START): Fix .prologue.  Set __libc_stack_end.
	* sysdeps/alpha/elf/start.S: Pass sp as arg 7.  Kill __data_start.

	* sysdeps/alpha/fpu/fraiseexcpt.c (feraiseexcept): Mark tmp
	as early-clobber.

	* sysdeps/libm-ieee754/e_exp10.c: Include "math_private.h".
	* sysdeps/libm-ieee754/e_exp10f.c: Likewise.
	* sysdeps/libm-ieee754/e_exp10l.c: Likewise.
