For example when I try to test my build with the mingw32 cross-compiler, I regularly get this error after the build system tried to re-create the configuration with the config.status file: ERROR: sizeof(size_t) doesn't match GLIB_SIZEOF_SIZE_T. You probably need to set PKG_CONFIG_LIBDIR to point to the right pkg-config files for your build target A similar problem exists for the "windres" tool, where you have to set the WINDRES variable in case it has a different name. So let's fix these issues by storing the configuration for these variables in the config.status file, too.
