Looks fine to me.  Thanks!

I would treat this as an orthogonal (sub-)problem.  We should always define 
APR_HAS_SENDFILE and move in the logic for emulating sendfile into 
apr_socket_sendfile.  This would clean up a major wart in our interfaces that 
we should have dealt with long ago and enables us not to have to return 
APR_ENOTIMPL.

Yet, this can be treated separately from any _AUTODETECT code.

Does that make sense?  -- justin
