Fri Jun 28 02:41:08 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>cvs/libc-960628

	* nss/Makefile (databases): New variable.
	(routines, libnss_files-routines): Use it.
	(subdir-dirs): Compute from $(services).

	* sysdeps/unix/sysv/linux/syscalls.list (create_module, delete_module,
	init_module, klogctl): Use EXTRA in the "caller" column so these get
	added to unix-extra-syscalls and thus compiled in misc.

	* string/Makefile (routines): Add strndup.
	* string/strndup.c: New file.
	* string/string.h: Declare strndup.
	(strndupa): New macro.

	* string/string.h: Declare __strdup.
	* string/strdup.c: Deansideclized.  Define __ name and weak alias.

	* string/string.h: Don't define memccpy as macro for [__OPTIMIZE__].

Thu Jun 27 23:43:22 1996  Richard Henderson  <rth@tamu.edu>

	* sysdeps/alpha/dl-machine.h (elf_machine_rela):  The Alpha's
	address-of operation and plt format conspire to require all
	dynamic relocs to be resolved to actual symbols not plt entries.

Thu Jun 27 02:49:28 1996  Ulrich Drepper  <drepper@cygnus.com>

	* catgets/gencat.c: Add casts to avoid signed<->unsigned warnings.

	* grp/initgroups.c (initgroups): De-ansi-fy.
	Move declaration of NGROUPS and GROUPS outside #if so that
	the code compiles for NGROUPS_MAX != 0.

	* inet/Makefile (headers): Add netinet/ether.h and netinet/if_ether.h.
	(routines): Add ether_aton, ether_aton_r, ether_hton, ether_line,
	ether_ntoa, ether_ntoa_r, and ether_ntoh.
	* inet/ether_aton.c, inet/ether_aton_r.c, inet/ether_hton.c,
	inet/ether_line.c, inet/ether_ntoa.c, inet/ether_ntoa_r.c,
	inet/ether_ntoh.c: New files.  Implementation of functions to
	handle Ethernet address to host mapping.
	* inet/netinet/ether.h: New file.  Declare ether_* functions.
	* netinet/ether.h: Wrapper around inet/netinet/ether.h for glibc
	compilation.
	* nss/ethers-lookup.c: New file.  Lookup function for ethers database.
	* nss/Makefile (routines): Add ethers-lookup.
	(libnss_files-routines): Add files-ethers.

	* nss/getXXent_r.c: Don't define set*ent and end*ent function
	with _r suffix.

	* nss/nss_files/files-XXX.c (internal_endent): Don't reset
	KEEP_STREAM every time called.
	(_nss_files_end): Reset KEEP_STREAM here instead.
	(internal_getent): If STREAM == NULL try to open instead of
	signalling error.
	Use cast to prevent warning.
	Terminate read line in case the buffer is too small.

	* nss/nss_files/files-ethers.c: New file.  Implementation of
	Ethernet adress<->hostname lookup through files interface.

	* stdlib/mbstowcs.c: Define based on mbsrtowcs().
	* stdlib/mbtowc.c: Define based on mbrtowc().
	* stdlib/wcstombs.c: Define based on wcsrtombs().
	* stdlib/wctomb.c: Define based on wcrtomb().

	* sunrpc/xdr.c (xdr_u_int): Avoid bogus call to
	unexpected_sizes_in_xdr_u_int.

	* sysdeps/generic/netinet/if_ether.h: New file.  Generic declaration
	of `struct ether_addr'.
	* sysdeps/unix/sysv/linux/netinet/if_ether.h: New file.  Linux specific
	declaration of `struct ether_addr'.

	* wcsmbs/mbrtowc.c: Handle case where argument PS is NULL.
	* wcsmbs/mbsrtowcs.c: Ditto.
	* wcsmbs/wcrtomb.c: Ditto.
	* wcsmbs/wcsrtombs.c: Ditto.

	* wcsmbs/mbsinit.c: Prepare for PS being NULL.
