+       * mempcpy.m4: New file, taken from gnulib.
+       * getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Renamed from
+       GL_FUNC_GETCWD_PATH_MAX for consistency.  All uses changed.
+       Use the _ONCE methods, for efficiency.
+       Check for fcntl.h.  In test program, include <errno.h>
+       and <fcntl.h> if available.  Remove old K&R cruft from
+       test program.  Check for common errors in GNU/Linux,
+       OpenBSD, and Solaris.  Just set gl_cv_func_getcwd_path_max;
+       don't do AC_LIBOBJ, as that's getcwd.m4's job.
+       * getcwd.m4 (gl_FUNC_GETCWD_NULL): Renamed from
+       AC_FUNC_GETCWD_NULL.  All used changed.  Change cache variable
+       name accordingly.
+       (gl_FUNC_GETCWD, gl_PREREQ_GETCWD): New macros.  Revamp to
+       accommodate new getcwd.c.
+       * jm-macros.m4 (gl_MACROS): Don't require GL_FUNC_GETCWD_PATH_MAX.
+       * prereq.m4 (gl_PREREQ): Add gl_FUNC_MEMPCPY.
+       * xgetcwd.m4 (gl_XGETCWD): Replace with gl_FUNC_GETCWD, since
+       that's all we need now.

        * utimens.m4 (gl_UTIMENS): Check for futimes function.
