/**

 * @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.
