minor strftime.c changes

[Jim Meyering]

The first change avoids a warning about an unused function.
The second avoids a compile warning or failure with some non-gcc compiler.

2003-04-11  Jim Meyering  <address@hidden>

        * time/strftime.c (my_strftime_localtime_r): Include this function
        definition in the `#if ! HAVE_TM_GMTOFF' block.
        (widen): Cast alloca return value to proper type.
