As far as I know, the type 'size_t' is C-standard. If it is not defined
on your platform, you will have problems with the socket layer also. If
it is not defined, defining it in your port's 'cc.h' will be the right
thing to do.

'mem_size_t' can't be used here since lwIP allows using the C library's
malloc functions, which are standardized to use 'size_t'.
