I believe this should be mostly obsolete. GRE has been incorporated into
STABLE on 1st December, so you shouldn't need to patch anything any
more. Probably you will just have to configure a gre interface and make
squid talk to that.

Yep, this sounds like the patch has already garbled your ip_var.h and
ip_gre.h files and has thrown in superfluous declarations.
