Require GpgRT version 1.41.
* configure.ac (NEED_GPG_ERROR_VERSION): Rename to NEED_GPGRT_VERSION and set to 1.41. * common/sysutils.c (gnupg_access): Remove code for older gpgrt versions. * kbx/backend-sqlite.c: Ditto. * sm/gpgsm.c (main): Ditto.
We already have a requirement for a newer Libgcrypt and thus we can
also require a more recent libgpgrt (aka libgpg-error) which was
released before Libgcrypt.
