#include "hconfig.h"

Cutover various gen*.c files to using system.h:
* Makefile.in (genconfig.o, genflags.o, gencodes.o, genemit.o,
genopinit.o, genrecog.o, genextract.o, genpeep.o, genattr.o,
genattrtab.o, genoutput.o): Depend on system.h.
* genattr.c: Include system.h. Add arguments to various function
prototypes. Remove redundant prototype of read_rtx().
* genattrtab.c: Likewise.
* gencodes.c: Likewise.
* genconfig.c: Likewise.
* genemit.c: Likewise.
* genextract.c: Likewise.
* genflags.c: Likewise.
* genopinit.c: Likewise.

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.

genopinit, genrecog, genextract, genpeep, genattr, and
