dnl Check for socklen_t: historically on BSD it is an int, and in
|
|
dnl POSIX 1g it is a type of its own, but some platforms use different
|
|
dnl types for the argument to getsockopt, getpeername, etc. So we
|
|
dnl have to test to find something that will work.
|
|
|
|
dnl On mingw32, socklen_t is in ws2tcpip.h ('int'), so we try to find
|
|
dnl it there first. That file is included by gnulib's socket_.h, which
|
|
dnl all users of this module should include. Cygwin must not include
|
|
dnl ws2tcpip.h.
