	PR fortran/86248
	* resolve.c (flag_fn_result_spec): Correct a typo before the
	function declaration.
	* trans-decl.c (gfc_sym_identifier): Boost the length of 'name'
	to allow for all variants. Simplify the code by using a pointer
	to the symbol's proc_name and taking the return out of each of
	the conditional branches. Allow symbols with fn_result_spec set
	that do not come from a procedure namespace and have a module
	name to go through the non-fn_result_spec branch.
