Re: slapd fails to start up in 2.3.8 and 2.3.9

[Howard Chu <hyc@symas.com>]

errno 38 is ENOSYS, it seems the epoll_ctl system call is not 
implemented on your target kernel. You say that running "make test" 
works though? That's pretty strange. You'll probably have to set 
ac_cv_header_sys_epoll_h = no and rerun configure. The configure script 
checks that epoll_create() works, strange that it would succeed but 
epoll_ctl() fails.
