Ebtables Compile errors with gcc4

I tried to compile 2.0.6 under FC4 using gcc4, and got numerous warnings. An 
internet search found possibile solutions to several gcc4 requirements for 
stricter coding guidelines, and I got a little futher, but still have not 
gotten  make to work without erors. Has anyone else gotten any furhter?

Thanks, Mike


Initial Make produced errors like this:

ebtables.c:583: warning: pointer targets in passing argument 1 of 
?print_mac_and_mask? differ in signedness

these errors are a result of cgg4's requirement to maintain proper signage

Editing Makefile line 8 to:

CFLAGS:=-Wall -Wunused -Wno-pointer-sign

makes the errors go away, but doesn't fix the base coding errors.

Running Make after this produces new error:

gcc -Wall -Wunused -Wno-pointer-sign -DPROGVERSION=\"2.0.6\" 
-DPROGNAME=\"ebtables\" -DPROGDATE=\"November\ 2003\" 
-D_PATH_ETHERTYPES=\"/etc/ethertypes\" -c -o ebtables.o ebtables.c 
-Iinclude/
ebtables.c: In function ?check_rule_exists?:
ebtables.c:1174: error: label at end of compound statement
make: *** [ebtables.o] Error 1

resulting from the use of empty label.
Changing program from:

letscontinue:
        }
        return -1;
}

to:

letscontinue:
	return -1;
        }
        return -1;
}

makes the error go away, but I don't know if it is correct.

Third compile after this correction yields:

gcc -Wall -Wunused -Wno-pointer-sign -DPROGVERSION=\"2.0.6\" 
-DPROGNAME=\"ebtables\" -DPROGDATE=\"November\ 2003\" 
-D_PATH_ETHERTYPES=\"/etc/ethertypes\" -c -o extensions/ebt_ip.o 
extensions/ebt_ip.c -Iinclude/
extensions/ebt_ip.c: In function ?parse?:
extensions/ebt_ip.c:316: error: invalid lvalue in assignment
make: *** [extensions/ebt_ip.o] Error 1

This line appears to be casting the first digit from strtoul into an 
unsigned
char. I'm pretty much lost at this point as to how to fix it.

(unsigned char) i = strtoul(argv[optind - 1], &end, 10);
