The only thing the Standard says is in this regard is that a hosted
environment must allow an object of at least 65,535 bytes to be
created (32,767 bytes for C89). This doesn't mean that multiple
objects of this size can be created or that multiple objects totaling
this limit must be allowed and it isn't specified whether the limit be
achievable via static or dynamic allocation. For more details you
will need to consult the documentation for your implementation.
