* sysdeps/powerpc/elf/libc-start.c: Use long in place of int for argc

	load, so as to work on both 32-bit and 64-bit.  Remove unnecessary
	casts.  Align __libc_stack_end to 8 bytes.

2002-09-20  Roland McGrath  <roland@redhat.com>

	* sysdeps/powerpc/fpu/s_lrint.c: Use strong_alias/weak_alias macros
	instead of asm for lrintf, __lrintf aliases.

	* sysdeps/powerpc/fpu/s_lrint.c (__lrint): Change union long array to
	int array for 32-/64-bit compatibility.
	From Steven Munroe  <sjmunroe@us.ibm.com>.
