+       * error.m4 (jm_PREREQ_ERROR):
+       Do not invoke AC_CHECK_FUNCS with strerror_r, as
+       AC_FUNC_STRERROR_R does that.
+       Check for strerror declaration.
+
+       * strerror_r.m4: Add copyright notice, as nontrivial m4 files
+       are supposed to have them these days.
+       (AC_FUNC_STRERROR_R): Always do char* test, so that it gets cached.
+       Merge changes from latest Autoconf CVS.
+       Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
+       and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
+       POSIX decided to standardize on the int flavor of strerror_r.
