* locale/programs/ld-ctype.c (set_one_default): New function, broken
|

out of ...
|
||||
(set_class_defaults): ... local function set_default here.
|
||||
Define set_default as a macro locally to pass constant parameters.
|
||||
(allocate_arrays, set_class_defaults): Use C99 for scope for each CNT,
|
||||
rather than a shared local.
|

|

* stdlib/rpmatch.c (try): New function, broken out of ...
|
||||
(rpmatch): ... local function here. Also, prototypify definition.
