This test exhibited a false positive: It reported that Cygwin supports a
ja_JP.EUC-JP locale. But this locale has MB_CUR_MAX = 1, leading to subsequent
test failures. This fixes it:

        Don't pretend that Cygwin has a ja_JP.EUC-JP locale.
        * m4/locale-ja.m4 (gt_LOCALE_JA): Add test for MB_CUR_MAX. Needed on
        Cygwin 1.5.x.
