After working on some other things, I come back to this issue.

I feel that something is not as it should be with my lwip. I can find  
nowhere in the h-files a function netif_set_hostname. I find the parameter  
LWIP_NETIF_HOSTNAME, but it is undefined. On the other hand, there is a  
parameter CYGIMP_LWIP_NETIF_HOSTNAME in net_lwip.h (and I defined it in  
config as 1). However, as far as I can see, this parameter is used  
nowhere. I am tempted to assume, that there is a naming problem - two  
names for something that should be uniquely named?
I am working with ecos, but I am not sure which version of lwip it  
includes. The last checkout (ecos)I did was sometimes this spring.....  
Prior to delving into further details: What is your opinion about this?
