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.
Have a nice day,
