Re: [Xen-devel] mini-os: gnttab.c does not compile

[Anil Madhavapeddy <anil@xxxxxxxxxxxxx>]

MiniOS wasn't declaring a __XEN_INTERFACE_VERSION__, so it broke  
after the recent dom0_ops.h change.
I pushed a small Makefile fix so it declares it as 0x00030203 (the  
version right before those changes) and builds again.  Someone should  
also update it to sync with the new header files as well so that the  
interface version can bumped to the latest.
