perhaps m4_ifndef([AC_C_RESTRICT], AC_DEFUN([gl_C_RESTRICT], [...] ]) ]) could be better. But: how many people are using current gnulib with Autoconf 2.57 or earlier? I know it is only two releases behind the latest, but OTOH, it is 3 years old. Current gnulib is mostly used for bootstraps of CVS checkouts, so I guess requiring Autoconf 2.59 may not be a bad idea.
