dnl Test for libgpg-error and define GPG_ERROR_CFLAGS, GPG_ERROR_LIBS,
dnl GPG_ERROR_MT_CFLAGS, and GPG_ERROR_MT_LIBS.  The _MT_ variants are
dnl used for programs requireing real multi thread support.
dnl
dnl If a prefix option is not used, the config script is first
dnl searched in $SYSROOT/bin and then along $PATH.  If the used
dnl config script does not match the host specification the script
dnl is added to the gpg_config_script_warn variable.
