Reduce scope of variables declared inside a switch statement. OK, so
make those code snippets into blocks then, to reduce the scope of
those variables. Workaround for weird errors as reported by gcc 4.2.1
in the 10.6 SDK:

SalAquaPicker.cxx: In member function 'void SalAquaPicker::implInitialize()':
SalAquaPicker.cxx:134: error: jump to case label
SalAquaPicker.cxx:127: error:   crosses initialization of 'NSNumber* pExtn'
SalAquaPicker.cxx:126: error:   crosses initialization of 'NSUserDefaults* pDefaults'
SalAquaPicker.cxx:141: error: jump to case label
SalAquaPicker.cxx:127: error:   crosses initialization of 'NSNumber* pExtn'
SalAquaPicker.cxx:126: error:   crosses initialization of 'NSUserDefaults* pDefaults'
