* sysdeps/hppa/bits/setjmp.h: Add _BITS_SETJMP_H preprocessor

	protection and allow pthread.h to include bits/setjmp.h as well as
	setjmp.h.
	* sysdeps/m68k/bits/setjmp.h: Likewise.
	* sysdeps/s390/bits/setjmp.h: Make sure only setjmp.h or pthread.h
	are allow to include bits/setjmp.h.
	* sysdeps/mips/bits/setjmp.h (_JMPBUF_UNWINDS): Cast rhs to match lhs
	cast of address.
	* sysdeps/sh/bits/setjmp.h: Likewise.

2005-11-12  Jim Meyering  <jim@meyering.net>

	* sysdeps/unix/opendir.c (__alloc_dir): Declare STATP parameter
	to be pointer to const.
	* include/dirent.h: Update decl.
