…mp.h as LibC itself supports mkstemp functionality
Merge from branch with one main difference: the default save_path is set to the empty string on all platforms, whereas the code in the branch only does so for win32.
windows sockets. The winsock implementation will only work with sockets; our implementation works with sockets and file descriptors. By association, stream_select() will now operate correctly with files, pipes and sockets. This change required linking against the winsock2 library. In terms of compatibility, only older versions of windows 95 do not have winsock2 installed by default. It is available as a redistributable file, and is most likely installed by any OS patches (eg: Internet Explorer) applied by the user. Also, add a win32 compatible pipe test when opening a stream from a pipe. This test will only work on NT, win2k and XP platforms. Without this test, interleaved fread() and select() calls would cause the read buffer to be clobbered. I will be working on a fix for this issue for win9x.
