{ 0 } is the only portable initializer for an mbstate_t. If we were to use
another initializer, it would make assumptions about the structure of an
mbstate_t. That is, #ifdefs.
Another option was to use to portable initializer, but use
memset (&s, '\0', sizeof (s)) to initialize the variable.
This is ugly BSD style of the 1980ies, which we have abandoned
more than 10 years ago.
