Hello,

FD_SETSIZE must be >= CONFIGURE_LIBIO_MAXIMUM_FILE_DESCRIPTORS. You can 
define FD_SETSIZE yourself, however, this is quite brittle since you 
must do this for every include of <sys/select.h> (e.g. also in external 
libraries). A better alternative to select() is kqueue() if you use the 
libbsd.
