+       (_GL_ATTRIBUTE_FORMAT, _GL_ATTRIBUTE_FORMAT_PRINTF): New macros.
+       (dprintf, fprintf, obstack_printf, obstack_printf, obstack_vprintf,
+       printf, snprintf, sprintf, asprintf, vasprintf, vdprintf, vfprintf,
+       vsnprintf, vsprintf): Use _GL_ATTRIBUTE_FORMAT_PRINTF.

+       stdlib: don't get in the way of non-GCC __attribute__
+       See thread starting at
+       <http://lists.gnu.org/archive/html/bug-gnulib/2011-02/msg00161.html>.
+       Revert previous stdlib change, installing the following instead:
+       * lib/stdlib.in.h (__attribute__): Remove.  We do not want
+       to get in the way of a non-GCC compiler that supports __attribute__.
+       (_GL_ATTRIBUTE_RETURN): New macro.
+       (_Exit): Use it instead of __attribute__.
