could be totally optional, for in win32_threads.c it is only used as
# if defined(THREAD_LOCAL_ALLOC)
GC_push_all((ptr_t)(&GC_thread_key),
(ptr_t)(&GC_thread_key)+sizeof(&GC_thread_key));
/* Just in case we ever use our own TLS implementation. */
# endif
Since ECL does not use thread_local_alloc, if the garbage collector also
doesn't, then one could drop that part and be able to do what you expect.
Otherwise, removing the declspec() would be just doomed to fail, for the
collector would expect it to have a different value for each thread.
