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

	* nss/getXXent_r.c: Likewise.

	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.
