I'm a bit disappointed that, when looking into the sources anyway, why
nobody provides a patch, rather then let me go through the whole test
again. Sigh.
Here's another problem: Bruno is wrong. Cygwin has it's own implementation
of __eucjp_wctomb and __eucjp_mbtowc in winsup/cygwin/strfunc.cc, using
the underlying Windows functions WideCharToMultiByte/MultiByteToWideChar.
The newlib functions don't need to be rewritten.
Thanks all the same for the testcase.
