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
