[Box Backup] Crosscompiling boxbackup-0.10 for a Router (freetz)

[Mirko]

Hi,

I am trying to compile boxbackup-0.10 for freetz (http://www.freetz.org). 
Freetz is a FW-Mod for the AVM Fritz!Box which is a popular home-router in 
Germany.

After I persuaded "configure" to no longer complain I get the following 
compile time error:

-----------------------------------
Do you happen to know, why the sources won't compile in this way?

Cheers, Mirko
