	* i386-gen.c (table): New.
	(process_i386_opcodes): Report errno when faied to open
	i386-opc.tbl.  Output opcodes to table.  Close i386-opc.tbl
	before return.
	(process_i386_registers): Report errno when faied to open
	i386-reg.tbl.  Output opcodes to table.  Close i386-reg.tbl
	before return.
	(main): Open i386-tbl.h for output.

	* Makefile.am ($(srcdir)/i386-tbl.h): Remove " > $@".
	* Makefile.in: Regenerated.
