	passed to OPERATE.
	(_dl_receive_error): Likewise.
	* elf/link.h: Change prototypes for _dl_catch_error and
	_dl_receive_error to reflect above change.
	* elf/dl-deps.c: Don't use nested function.  Call _dl_catch_error
	with additional argument with pointer to data.

1997-03-28 21:14  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* elf/dl-error.c: Manually set up the values of "c", this avoids a
	call to memcpy and a zero 152 bytes structure.

	* sysdeps/sparc/dl-machine.h (elf_machine_rela): Test
	RTLD_BOOTSTRAP to avoid performing relative relocs on a second
	pass.

	* sysdeps/sparc/udiv_qrnnd.S: Make the code PIC aware.

	* sysdeps/unix/sysv/linux/sparc/Dist: Add kernel_stat.h and
	kernel_sigaction.h

	Add Linux/SPARC specific definitions.
	* sysdeps/unix/sysv/linux/sparc/fcntlbits.h: New file.
	* sysdeps/unix/sysv/linux/sparc/ioctls.h: New file.

	__getservbyname_r() not getservbyname().
	(BROKEN_LIKE_POSIX): Define to 1 so we get strict POSIX behaviour.
