Cross compile

So I was trying to cross compile and nim compiler said something to choose, posix.SocketHandle or winlean.SocketHandle so I changed to code again.

when defined(windows):

import winlean

import posix
import times
import nativesockets

when defined(windows):
const
libname = "libssh2.dll"
elif defined(macosx):
const
libname = "libssh2.1.dylib"
elif defined(unix):
const
libname = "libssh2.so.1"

{.pragma: ssh2,
cdecl,
dynlib: libname,
importc: "libssh2_$1"
.}

It returns LIBSSH2_ERROR_EAGAIN when it would otherwise block.
