 * @file include/mhd_options.h
 * @brief  additional automatic macros for MHD_config.h
 * @author Karlson2k (Evgeny Grin)
 *
 * This file includes MHD_config.h and adds automatic macros based on values
 * in MHD_config.h, compiler built-in macros and commandline-defined macros
 * (but not based on values defined in other headers). Works also as a guard
 * to prevent double inclusion of MHD_config.h

 * Macro to make it easy to mark text for translation. Note that
 * we do not actually call gettext() in MHD, but we do make it
 * easy to create a ".po" file so that applications that do want
 * to translate error messages can do so.
