[PATCH/RFA] Internationalize ctype functionality

[Antony King]

Hi,

I have a customer complaining that some static libraries (supplied by a
3rd party) that had been built using the headers from an older version
of newlib (1.16.0) no longer link with the latest version of newlib
(1.18.0) due to the deletion of the __ctype_ptr variable from ctype_.c
due to the following change:

(see http://sourceware.org/ml/newlib/2009/msg00370.html)

Would it be safe to re-introduce the definition of this variable back
into ctype_.c with the attached patch ?

[I know this query is coming long since the change was made but this
issue has only just come to light :-(.]

Cheers,

Antony.
