* @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.
