On the other hand, it builds this correctly:
configure:8114: checking for compiler -fshort-wchar option
configure:8128: c++ -c -fno-strict-aliasing -fshort-wchar conftest.C 1>&5
This being generated by the following configure.in snippet:
[AC_TRY_COMPILE([#include <stddef.h>
$configure_static_assert_macros],
[CONFIGURE_STATIC_ASSERT(sizeof(wchar_t) == 2);
CONFIGURE_STATIC_ASSERT((wchar_t)-1 > (wchar_t) 0)],
ac_cv_have_usable_wchar_option_v2="yes",
ac_cv_have_usable_wchar_option_v2="no")])
This snippet is responsible for the addition of -fshort-wchar in the CXX_FLAGS
in
what is failing for you.
