	* stdlib/tst-strtol.c (tests): Correct 64-bit entry.

	* sysdeps/alpha/bsd-_setjmp.S: Alias _setjmp to __setjmp for
	change to tst-setjmp.c.

	* sysdeps/alpha/dl-machine.h: Mirror Roland's recent changes.
	* sysdeps/i386/dl-machine.h: Correct noexec_p comment.
	* sysdeps/sparc/dl-machine.h: Likewise.

	* sysdeps/libm-ieee754/s_remquo.c: Rename {hp,lp} -> {hy,ly}.
	Add missing qs variable.
	* sysdeps/libm-ieee754/s_remquof.c: Likewise.
