21  * @file platform.h
22  * @brief platform-specific includes for libmicrohttpd
23  * @author Christian Grothoff
24  *
25  * This file is included by the libmicrohttpd code
26  * before "microhttpd.h"; it provides the required
27  * standard headers (which are platform-specific).<p>
28  *
29  * Note that this file depends on our configure.ac
30  * build process and the generated config.h file.
31  * Hence you cannot include it directly in applications
32  * that use libmicrohttpd.
