111 If defined to 1, then the select backend will use the system fd_set
112 structure. This is useful if libev doesn't compile due to a missing
113 NFDBITS or fd_mask definition or it misguesses the bitset layout on
114 exotic systems. This usually limits the range of file descriptors
115 to some low limit such as 1024 or might have other limitations
116 (winsocket only allows 64 sockets). The FD_SETSIZE macro, set
117 before compilation, might influence the size of the fd_set used.
