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