FC6 forcedeth.c 0.62 errors and warnings during compile

[bobism]

I have a problem with my M2N-MX mob using the FC6 forcedeth.ko, versions 0.59 and 0.60 (latest kernel). The ethernet link will go "corrupt" and wont recover, ifdown/ifup wont help. If I reload the driver, it recovers e.g. rmmod/modprobe. So I'm trying to compile 0.62 source as supplied in NVIDIA 1.23;

http://www.nvidia.com/object/linux_nforce_1.23.html

However, when I compile the module using the following Makefile;

> obj-m := forcedeth.o
>
> KDIR := /lib/modules/$(shell uname -r)/build
> PWD := $(shell pwd)

> default:
> $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) clean
> $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules

I get the warnings and errors shown at the end of my post. What am I doing wrong? Please help!
