* dlfcn.cc (check_path_access): Call find_exec with FE_DLL option. 

* path.h (enum fe_types): Add FE_DLL value.
	* spawn.cc (std_suffixes): Remove.
	(exe_suffixes): New suffix_info for executing files.
	(dll_suffixes): New suffix_info for searching shared libraries.
	(perhaps_suffix): Add opt argument.  Use dll_suffixes if FE_DLL
	option is given, exe_suffixes otherwise.
	(find_exec): Propagate opt argument to perhaps_suffix.  Drop suffix
	check when testing execute permission.
	(spawn_guts): Call perhaps_suffix with FE_NADA opt argument.
