e88a135 Some platforms lack socklen_t type
Gary V. Vaughan authored
1 dnl Check for socklen_t: historically on BSD it is an int, and in
2 dnl POSIX 1g it is a type of its own, but some platforms use different
3 dnl types for the argument to getsockopt, getpeername, etc. So we
4 dnl have to test to find something that will work.
