Description Marc Glisse 2010-03-20 20:51:00 UTC 
Hello,

currently, wctype.h gets the definition of wint_t as follows:

/* Get wint_t from <stddef.h>.  */
# define __need_wint_t
# include <stddef.h>

On the other hand, wchar.h (which also supports inclusion with __need_wint_t) 
has a more elaborate strategy that works around gcc versions (and other 
compilers) that don't define wint_t (there is also mention of some namespace 
issue). Is it possible to change wctype.h to use the following?

/* Get wint_t from <wchar.h>.  */
# define __need_wint_t
# include <wchar.h>

I might reverse the change because it is dangerous to not use the definition
from stddef.h but for now I changed it along the lines suggested.
