Hi Bo,
 
 thanks for your fast reply, but unfortunately it does not completely
 solve it. Now I get this:

 Something seems to be rotten in my system...
 May be the linux kernel header files under /usr/linux and those of
 linux-2.6.18 are incompatible ???

 My includes are now:
    
    #include <linux/if.h>
    #include <linux/ethtool.h>
    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    #include <errno.h>
    #include <sys/types.h>
    #include <linux/types.h>
    #include <sys/socket.h>

 The program (a eth-link tester) is simply compiled with 

	 make <program>

 and I compile with gcc-4.1.1 (yse I did all the emerge system/world
 thingies and beside of this everything works fine until
 now). Compiling the kernel is as boring as ever ;O)


 Keep hacking!
