Update.

	* intl/locale.alias: Change italian to it_IT.ISO-8859-1.
	Reported by Ottavio G. Rizzo <otto@mast.queensu.ca>.

1998-05-08 19:24  Zack Weinberg  <zack@rabi.phys.columbia.edu>

	* Makefile (+subdir-inits): Delete variable.
	(+init_subdirs): Likewise.
	(aux): Likewise.
	(before-compile): Likewise.
	(libc-init): Delete stanza.
	(version-info.h): Delete rule and associated variable.
	(distribute): Don't distribute moved files.
	* Makerules (interp-obj): It lives in elf now.  Only use it
	if $(elf) is set.  Delete rule to build it.
	* csu/Makefile: Build set-init.o and/or munch-init.o.  Build
	version.o and version-info.h.  Minor cleanups.
	(routines): Add libc-init, sysdep, version.
	(generated): Add version-info.h.
	* elf/Makefile: Build interp.os.

	* interp.c: Moved to elf.
	* set-init.c: Moved to csu.
	* munch-init.c: Likewise.
	* munch.awk: Likewise.
	* version.c: Likewise.

	* Makeconfig: Add emacs mode marker.
	* Makerules: Likewise.
	* Rules: Likewise, and also unconfuse syntax highlighting with
	a fake comment.
