Hm. Actually, if the rest of the backend compiles without this, then
I guess the real question is what's zic.c doing that needs it? pg_ctl.c
has an excuse because it's doing weird MS-specific junk, but zic.c is
supposed to be bog-standard portable code. It really shouldn't have
anything that's further out there than you could find in ten other
places in the backend.
