Sure:
#import
int
main()
{
OFArray *array = [OFArray arrayWithObjects: @"a", @"b", nil];
int someVar = 0;
for (id object in array) {
switch (someVar) {
case 0:
OFLog(@"%@", object);
break;
}
OFLog(@"foo");
}
return 0;
}
Sorry, but something free-standing isn't possible as you need a collection
object. The same code should work with GNUstep by just replacing OF with NS.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=103639 --- Comment #2 from js-gcc at webkeks dot org --- Oh, forgot to clarify in the example: Assume more than 1 object in the collection and someVar to be 0.
