	* Makefile.in (build/read-md.o): Depend on errors.h.
	* read-md.h (error_with_line): Declare.
	* read-md.c: Include errors.h.
	(message_with_line_1): New function, extracted from...
	(message_with_line): ...here.
	(error_with_line): New function.
	* genattrtab.c: If a call to message_with_line is followed by
	"have_error = 1;", replace both statements with a call to
	error_with_line.
	* genoutput.c: Likewise.
	* genpreds.c: Likewise.
	* genrecog.c: If a call to message_with_line is followed by
	"error_count++;", replace both statements with a call to
	error_with_line.
	(errorcount): Delete.
	(main): Don't check it.
	* gensupport.c: If a call to message_with_line is followed by
	"errors = 1;", replace both statements with a call to error_with_line.
	(errors): Delete.
	(process_define_cond_exec): Check have_error instead of errors.
	(init_md_reader_args_cb): Likewise.  Don't set errors.
