Merge pull request #954 in CASA/casa from CAS-12208 to master
* commit 'c738bd268d0d3eb37426394bba0a0085ddf8455d':
RowTransformer.h has an unused variable that I missed cleaning up at the previous commit
CAS-12208 OSX warnings silenced except for cast related warnings in SDMDataObjectReader which will require more complex code reworking that is reasonable for this ticket.
