Actually the building packages include packages begin with "ISO ..."  , so
the libc_string package is ready in the building packages and the conflicts
are just the same as before.

/ecos-d/ecos/ecos/packages/net/lwip_tcpip/current/cdl/lwip_net.cdl, package
CYGPKG_NET_LWIP: error
    Interface `CYGPKG_NET_STACK' cannot be loaded.
    The name is already in use.
/ecos-d/ecos/ecos/packages/net/lwip_tcpip/current/cdl/lwip_net.cdl, package
CYGPKG_NET_LWIP: error
    Interface `CYGPKG_NET_STACK_INET' cannot be loaded.
    The name is already in use.
/ecos-d/ecos/ecos/packages/net/lwip_tcpip/current/cdl/lwip_net.cdl, package
CYGPKG_NET_LWIP: error
    Interface `CYGPKG_NET_STACK_INET6' cannot be loaded.
    The name is already in use.

BTW: How much memory will the lwip stack take? The at91sam7x256 has only 64k
ram and I don't know whether it's suitable for some internet applications.
Maybe I will get another arm board to develop the product. Any suggestion is
welcome, thanks!
