providing era_info and alt_digits pointers and call ...
(__strftime): Rename from strftime and make static if
_WANT_C99_TIME_FORMATS is defined. Add parameters for era_info and
alt_digits pointers. Handle conversion modifiers according to
POSIX-1.2008. Redefine %F and %Y according to POSIX. Add default case
to allow to bail out on invalid conversion specifiers.
