Thanks for the test. This means that the need for <stddef.h> arises because
wchar_t would otherwise not be defined. I'm committing this fix (equivalent
to your suggestion):


2011-04-14  Bruno Haible  <address@hidden>

        wchar: Ensure that wchar_t gets defined on uClibc.
        * lib/wchar.in.h: On uClibc, include <stddef.h>.
        Reported by Giuseppe Scrivano <address@hidden>.
