Ran all the source files through 'perl -pi' with this script: s|\s*(};?\s*)?/\*\s*(end\s*)?namespace\s*(\S+)\s*\*/(\s*})?|} // namespace $3|; s|\s*};?\s*//\s*(end\s*)?namespace\s*(\S+)\s*|} // namespace $2\n|; s|\s*};?\s*//\s*(\S+)\s*namespace\s*|} // namespace $1\n|; Also did a little manual editing on some of the arch/*/isa_traits.hh files and src/SConscript.
