Subject: errors.c: New file...

1999-08-27 00:27 -0700  Zack Weinberg  <zack@bitmover.com>

	* errors.c: New file; defines functions error, warning, and
	fatal, variables have_error and progname.
	* errors.h: New file; prototypes and decls for stuff in errors.c.

	* Makefile: Add rules to build errors.o and
	$(HOST_PREFIX)errors.o.  Link genconfig, gencodes, genemit,
	genopinit, genrecog, genextract, genpeep, genattr, and
	genoutput with errors.o.  Add errors.h to deps of genconfig.o,
	gencodes.o, genemit.o, genopinit.o, genrecog.o, genextract.o,
	genpeep.o, genattr.o, and genoutput.o.

	* genconfig.c, gencodes.c, genemit.c, genopinit.c, genrecog.c,
	genextract.c, genpeep.c, genattr.c:  Include errors.h.  Don't
	define or prototype fatal.  Set progname at beginning of main.
	* genoutput.c:  Likewise, and don't define or prototype error
	either.
