If the patch you are using is the patch I am thinking of, it only
patches the kernel, and not the library headers as well (as the previous
patch did).

Apparently the increased value of FD_SETSIZE is picked up, but there are
a couple other library constants that might get missed. Such is life. I
hand-hack around such inconveniences.
