2001-04-21  Franz Sirl  <Franz.Sirl-kernel@lauterbach.com>

	* sysdeps/unix/sysv/linux/powerpc/mmap64.c: Correct check for invalid
	offset.

2001-04-21  Ulrich Drepper  <drepper@redhat.com>

	* posix/getopt.h: Treat __cplusplus like __STDC__.

2001-04-20  John S. Marvin  <jsm@fc.hp.com>

	* sysdeps/unix/sysv/linux/hppa/clone.S: Fix clone system call
	entry point stub.

2001-04-20  Richard Hirst  <rhirst@linuxcare.com>

	* elf/elf.h: Corrected R_PARISC_DIR14R (should be 6, not 5),
	and added R_PARISC_DPREL21L and R_PARISC_DPREL14R for modutils.

	* sysdeps/unix/sysv/linux/hppa/syscalls.list: Removed ptrace
	entry so the ptrace.c wrapper is used.

2001-04-20  Alan Modra  <amodra@one.net.au>

	* sysdeps/hppa/dl-lookupcfg.h (_dl_function_address): Prototype.
	(DL_FUNCTION_ADDRESS): Define.
	(DL_DT_INIT_ADDRESS): Define.
	(DL_DT_FINI_ADDRESS): Define.
	* sysdeps/hppa/Versions: Add _dl_function_address.
	* sysdeps/hppa/dl-machine.h (ELF_MACHINE_START_ADDRESS): Define.
	* sysdeps/hppa/dl-symaddr.c (_dl_start_address): Rename to
	_dl_function_address.
