-dnl Usage: AC_C___ATTRIBUTE__
-dnl call AC_DEFINE for HAVE___ATTRIBUTE__ and __UNUSED__
-dnl if the compiler supports __attribute__, HAVE___ATTRIBUTE__ is
-dnl defined to 1 and __UNUSED__ is defined to __attribute__((unused))
-dnl otherwise, HAVE___ATTRIBUTE__ is not defined and __UNUSED__ is
-dnl defined to nothing.
