 (w32_bind, w32_connect, w32_listen, w32_accept, valid_socket)
 (w32_closesocket, w32_recvfrom, w32_shutdown) [HAVE_SOCKETS]: New
 functions for MinGW, emulate Posix sockets specified by file
 descriptors.
 pc/config.h (HAVE_GETADDRINFO, HAVE_SOCKADDR_STORAGE)
 (HAVE_SOCKETS) [__MINGW32__]: Define.
 pc/config.sed (HAVE_GETADDRINFO, HAVE_SOCKADDR_STORAGE)
 (HAVE_SOCKETS) [__MINGW32__]: Define.

 including windows.h.
 extension/filefuncs.c [HAVE_GETSYSTEMTIMEASFILETIME]: Define
 WIN32_LEAN_AND_MEAN before including windows.h.

 test/clos1way.awk: Don't use features of Posix shells, to allow this
 test to work on Windows.
 test/beginfile2.sh: Leave one blank between the left quote and the
 following slash.  Use non-absolute name for a non-existent file.
 This is to avoid breakage on Windows due to MSYS transformation of
 Posix style /foo/bar absolute file names.
 test/beginfile2.ok: Adapt to changes in beginfile2.sh.
