No question there, but wouldn't it be easier to test such a platform and then fallback to "unigned int" in case wchart is found to be a signed value ?

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)
