/*
 * This file is like the other compat header files in that it
 * tries to hide differences between systems. It is somewhat
 * different in that it doesn't present a "normal" interface
 * to the rest of the code, but instead defines its own macros
 * and functions. This is done since Win32 uses closesocket()
 * instead of close() for sockets, but it can't be remapped
 * since it already has a close() for file descriptors. Also,
 * this allows us to hide the fact that some systems use
 * fcntl() and some use ioctl(). The select() function is
 * included here even though it isn't strictly for sockets.
 * Just call this version if any of the file descriptors might
 * be sockets.
 *
 * This file must be included _after_ any other socket related
 * headers and any other compat socket fixup headers.
