The patch is not variable name renames only. Renaming the flags in 5.1
would not be very meaningful without bug fix as the new names are 
misleading without it.

We have discussed making the whole patch for 5.1, but this was thought
to be a bit too risky.

What we can do, is to add backward compatible defines to 5.5 like I 
suggested in my initial e-mail.
