 > 	Detect local symbol name colliding with parameter. Track line number

 > 	(do_formals): Move local variable name to wider scope. Check
 > 	parameter of the same name doesn't already exist. In MRI mode, also
 > 	check it doesn't collide with the argument count pseudo-parameter).
 >	(define_macro): Add file and line number parameters. Remove local
 >	variable namestr. New local variable error. Initialize macro_entry
 >	members file, line, and name. Don't return when encountering an
 >	error, just record the fact. Use %s in some diagnostics for read.c
 >	to insert the macro name. Free macro_entry on error.
 >	(macro_expand): Pass macro_entry to macro_epand_body. Don't return
 >	when encountering an error, just record the fact.
 >	(expand_irp): Don't return when encountering an error, just record
 >	the fact.
 >	* macro.h (macro_struct): New members name, file, and line.
 >	(define_macro): Add file and line number parameters.
 >	* read.c (s_macro): Pass file and line to define_macro. Tag warning
