/**
 * @file platform.h
 * @brief platform-specific includes for libmicrohttpd
 * @author Christian Grothoff
 *
 * This file is included by the libmicrohttpd code
 * before "microhttpd.h"; it provides the required
 * standard headers (which are platform-specific).<p>
 *
 * Note that this file depends on our configure.ac
 * build process and the generated config.h file.
 * Hence you cannot include it directly in applications
 * that use libmicrohttpd.
