This patch is OK.  Thanks.

I don't understand why locale_init.cc is giving an aliasing warning at
all.  The line seems to b
    return reinterpret_cast<const locale&>(c_locale);
c_locale is a char array, and as such may be aliased to anything.  Did
TYPE_NONALIASED_COMPONENT somehow get set for the type of c_locale?
