[CentOS] Build fails on new kernel source

On my x86_64, I pulled down the source for the 2.6.18-92.1.13 kernel
and followed the wiki faithfully, but it will not build.  I'm getting
errors in the Buslogic driver:

It seems like a simple enough error to correct, but it seems kind of
odd that it would occur in the first place - redefinitions of "true"
and "false"?

Is anyone else seeing this?

Thanks.
