porting bird to ecos

Hi, I am trying to port BIRD to eCos. I configured BIRD for BSD as eCos has BSD tcp/ip stack and only enabled RIP as routing protocol. The problem that I face is that fcntl(fd, F_SETFL, O_NONBLOCK) fails while applying the configrations and ends up in calling the method called bug. If I comment the fcntl call than somwhere down die is invoked. Has anybody tried porting BIRD to eCos? Please help in identifying what could be possibly wrong here?
