[bug-gnulib] FYI: posixtm.c nit

[Jim Meyering]

Here's another one that was detected by gcc-4's -Wuninitialized,
but unlike for human.c, this time it's a false alert.

I've checked this in for gnulib and coreutils.

        * posixtm.c (posixtime) [lint]: Avoid spurious warning from gcc-4's
        -Wuninitialized: initialize tm0.tm_year.
