** Using ECL on iOS
The Boehm-Demers-Weiser garbage collector cannot find the stack base
automatically on iOS. Therefore, this has to be specified manually. In
the main function, before calling cl_boot, add e.g. (see the garbage
collector documentation for more details):
#+BEGIN_SRC C
const int size = 256;
char* ecl_argv[size];
GC_allow_register_threads();
GC_register_my_thread((const struct GC_stack_base*)ecl_argv);
GC_stackbottom = (char*)(ecl_argv + size - 1);
