* sysdeps/powerpc/bits/setjmp.h [__WORDSIZE]: Add 64-bit jmpbuf.

	* sysdeps/powerpc/bits/wordsize.h: New file.
	* sysdeps/powerpc/fpu/bits/mathinline.h (lrint, lrintf): Change long
	array to int array for 32-/64-bit compatibility.

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

	* login/programs/utmpdump.c: Don't include <error.h>, <errno.h>.

	* sysdeps/generic/utimes.c (__utimes): Don't check TVP for null.
	Reported by Bruno Haible <bruno@clisp.org>.

	* sysdeps/generic/ifreq.h (__ifreq): Compute termination condition
	before doubling RQ_LEN.
	* sysdeps/unix/sysv/linux/ifreq.h (__ifreq): Likewise.
	Reported by Bruno Haible <bruno@clisp.org>.

2002-09-18  Bruno Haible  <bruno@clisp.org>

	* login/logout.c (logout): Don't assume ut_time has the same size as
	a time_t.
	* login/logwtmp.c (logwtmp): Likewise.

	* sysdeps/pthread/configure: New file, moved here from
	linuxthreads/sysdeps/unix/sysv/linux/configure.
