Do you think adding a break in the loop after detecting such case is 
good?For example:

         delete_flag = 1;
         for(i=0; i<sizeof(tests)/sizeof(tests[0]); i++) {
             errno = 0xdeadbeef;
             SetLastError(0xdeadbeef);
             ret = p_tr2_sys__Symlink(tests[i].existing_path,
    tests[i].new_path);
             if(ret==ERROR_PRIVILEGE_NOT_HELD ||
    ret==ERROR_INVALID_FUNCTION) {
                 delete_flag = 0;
                 tests[i].last_error = ret;
                 win_skip("Privilege not held or symbolic link not
    supported, skipping symbolic link tests.\n");
    +              break;
             }
       }



Thank you.
