Hmm?

Hmm... Perhaps it's recent change, but with GCC 4.4 everything works fine:
$ cat test.c
#include <stdio.h>

int main(int argc, char **argv) {
  __extension__ (({
    switch (argc) {
      case 0 ... 5:
        printf("0 ... 5");
        break;
      default:
        printf("default");
        break;
    }
  }));
  return 0;
}
$ gcc --version
