IMO using 'const' before the type looks more natural. Also adding 'const' to all type conversions wouldn't hurt:
const impl* This = (const impl*)((const char*)(iface) - offsetof(impl,field))
That means something completely different. 'const impl* This' and 'impl* const This' are not the same thing.
Right, I think that const pointer is not what James had in mind, but a const area pointed out by a pointer.
