Good question, I need some advice. The Xen hcall headers get soft-linked into 
every paravirtualized OS tree: linux, bsd, solaris, etc. In linux right now the 
xen version.h shows up as  /include/asm-xen/version.h.

This file uses typedefs for every important parameter. For example, typedef char [1024] xen_capabilities_info_t;. But as Greg says TYPEDEFS ARE EVIL. Last resort would be to use the funky gcc #include_next to override the xen hcall headers with a linux-specific hcall headers. But I don't know if that would be cool with lkml either. So, advice would be welcome :). thanks,
