Where the ABI has changed between 4.2 and 4.3 the SONAMEs should also
have been bumped. The last missing bumps should have been caught by:

            tools: Bump some library sonames

Please let us know if we missed one.

We don't (usually) bump the SONAME more than once during a dev cycle so
if the ABI changed more than one things built against intermediate
versions may not work and would need rebuilding.

If you haven't recompiled then you may also be picking up the 4.2
SONAMEs (i.e. the 4.2 versions of the libraries), which wouldn't be
expected to work with 4.3.

Some good news for once - I can confirm our app compiles without a single
warning against 4.3-rc2. We'll try some unit tests next week.
