The XEmacLite_Config struct has 6 members, but is only initialized with
5 (PhysAddress is missing), so the TxPingPong is set with Rx value and
RxPingPong is always 0. If it has been set in HW, the driver will
assume that it is not set and will not work.

I guess I had these compilation errors because I choosed a config 
different to the default one. More explanations:

- in busybox/gzip: "static const int build_bl_tree() {...}"
has a declaration different from the prototype, and the "const"
has no sense as the result from the function.

- in busybox/inetd: "#define SWAP [...] (type)a=(type)b; [...]"
gcc does not accept a cast on the lvalue. This was accepted with
a previous version, but not anymore.

- in busybox/inetd: "vfork_daemon_rexec(argc, argv, "-f")"
vfork_daemon_rexec() is defined with two more parameters. I found
some patchs in uClinux and applied them on the code.

Note however that I could get gzip working, but not inetd. I did
not investigate further and just switch back to the stand alone inetd.
The patch at least correct the compilation problem, but I do 
not know if inetd's failure is related with it.

Regards,

Antoine
