	Redefine to not generate any runtime error check calls.
	(set_parameter_value_chk): Rename of the former
	set_parameter_value with the runtime error checks and fix
	whitespace. (set_parameter_value_inquire): New function that
	builds a runtime conditional block to set the INQUIRE
	common parameter block unit number to -2 when unit numbers
	exceed positive KIND=4 limits. (gfc_trans_open): Whitespace.
	For unit, use the renamed set_parameter_value_chk.
	(gfc_trans_close): Likewise use renamed function.
	(build_filepos): Whitespace and use renamed function.
	(gfc_trans_inquire): Whitespace and for unit use
	set_parameter_value and set_parameter_value_inquire.
	(gfc_trans_wait): Remove p->iostat from call to
