           Summary: clang stddef.h does not define wint_t
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Headers
        AssignedTo: unassignedclangbugs at nondot.org

In g++ 4.4.3 (possibly earlier):

The code:

'#include <wctype.h>' fails on clang, as stddef.h defines (via a series of
macros and ifdefs):

typedef unsigned int wint_t;

On the other hand

#include <wchar.h>
#include <wctype.h>

works correctly on both compilers, as wchar.h defines wint_t if it is not
otherwise defined.

This blocks some boost files when using g++ 4.4.3 as the underlying compiler.
