This inaccurate comment created by configure [from 2.3b1] implies that
sds/2 already expects wchar_t to be unsigned if it is to be usable:
  if test "$unicode_size" = "$ac_cv_sizeof_wchar_t"
  then
    PY_UNICODE_TYPE="wchar_t"
    AC_DEFINE(HAVE_USABLE_WCHAR_T, 1,
    [Define if you have a useable wchar_t type defined in wchar.h; useable
     means wchar_t must be 16-bit unsigned type. (see
     Include/unicodeobject.h).])
    AC_DEFINE(PY_UNICODE_TYPE,wchar_t)
... but configure doesn't actually check for signedness, and the "16-bit"
part is inaccurate. (it must be 16 bits for ucs-2, or 32-bits for ucs-4)
