Hi Matthew, My understanding from previous conversations is that backward-compatibility is not being provided for the next release, as such it is unlikely that backward-compatibility for compile/linking will be provided. I don't see how this particular patch would force people to change their code, though in all likelihood they will have to as a result of ABI changes in the following release. The only difference now would be when they link their applications against a single library instead of multiple separated libraries. Thanks, Sergio
