I'm curious: src/lib/libz/infcodes.c has

      {
      /* XXX work around a gcc bug. */
      volatile inflate_blocks_statef *s1 = s;

      while (f < s1->window)            /* modulo window size-"while" instead */
        f += s1->end - s1->window;      /* of "if" handles invalid distances */
      }

IIrc, Bruce Evans came up with this workaround. Does anyone know if this bug
has been fixed? It also pertains to net/rsync (patch-infcodes.c).
