@alja, this does not work on slc5 where we have gcc462 compiler. We get following compilation errors, can you please fix this for 53X as soon as possible.

Fireworks/Core/src/FWConfigurationManager.cc:245:76: error: expected ';' at end of member declaration
Fireworks/Core/src/FWConfigurationManager.cc:245:78: error: 'override' does not name a type

also for Fireworks/FWInterface/src/FWFFHelper.cc
I think just dropping the override keyword should be enough

@smuzaffar

I have removed override statement and checked build on slc5_amd64_gcc462.
The change is in the same branch alja:53-backport .

Should I make a new PR?
