	getaliasname_r.
	* aliases.h: New file.
	* inet/aliases.h: New file.
	* inet/getaliasent.c: New file.

	* nss/Makefile (databases): Add alias.
	* nss/alias-lookup.c: New file.
	* nss/databases.def: Add aliases and publickey.
	* nss/nss_db/db-alias.c: New file.

	description header.

Sat Nov  9 02:06:17 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/Makefile ($(common-objpfx)s-proto.d): Don't depend
	on $(before-compile) which hasn't been properly setup yet at this
	point.

Sat Nov  9 02:02:48 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/generic/sigset.h: Don't use implicit int which will
	probably require a diagnostic in the next revision of the C
	standard.
	* sysdeps/stub/lockfile.c: Likewise.

Sat Nov  9 01:57:17 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
