[CentOS] Compiling Broadcom netxtreme2-7.6.62 drivers Xen4CentOS

Having problems compiling Broadcom netxtreme2-7.6.62 drivers using the Xen4CentOS (http://wiki.centos.org/QaWiki/Xen4) kernel:

CentOS release 6.4 (Final)
3.4.61-9.el6.centos.alt.x86_64

I had to modify the Makefile's a little to get to pass the validation since it was referring to kernel 3.0 and 3.5 but not 3.4. But after doing this I still had the following problem:

# make

Is there anything I can do about this? The kernel is based on: Linux Kernel 3.4.x (kernel.org long term stable kernel).       

I have started a thread on Broadcom forums but there has not been a response. Has anyone been able to get them working?
