Pass flags to fcntl(F_SETFL) and fcntl(F_SETFD) as int, not long

Browse Source 
Everybody but Linux documents this as taking an int, and Linux is
very tolerant of getting an int instead.  If it weren't, everybody
doing fcntl(fd,F_SETFL,O_NONBLOCK) would break, since the glibc
headers define O_NONBLOCK as an int literal.
