The unused attribute can be used on a type.
typedef int I1 __attribute__ ((unused));
typedef int I2 __attribute__ ((section (".sec")));
foo.c:2: error: section attribute not allowed for âI2â
There is no error for I1.
What the unused attribute means for a type I decline to speculate. But
it is accepted where type attributes are accepted. Perhaps this is a
bug. I'm really not sure.
