New submission from Atsuo Ishimoto <ishimoto at gembook.org>:

When I use Py_UNICODE_ISSPACE() in my C++ extension, I got following error.

test.obj : error LNK2019: unresolved external symbol
"__declspec(dllimport) unsigned char const * const _Py_ascii_whitespace"
(__imp_?_Py_ascii_whitespace@@3QBEB) referenced in function "struct
_object * __cdecl fff(struct _object *,struct _object *)"
(?fff@@YAPAU_object@@PAU1 at 0@Z)

Py_ascii_whitespace defined in unicodeobject.h should be enclosed by
'extern "C" {' block for C++ support.

Tested with Python 2.6.1/VS2008 express.
