Changes in v16: * Rebased on top of trunk * Improved clarity of the commit message * Simplified Make-lang.in and gperf struct Changes in v15: * Rebased on top of trunk * Use gperf to look up traits instead of enum rid Changes in v14: * Added padding calculation to the commit message Changes in v13: * Fixed ambiguous commit message and comment Changes in v12: * Evaluated all paddings affected by the enum rid change Changes in v11: * Merged all patches into one patch series * Rebased on top of trunk * Unified commit message style * Used _GLIBCXX_USE_BUILTIN_TRAIT Ken Matsui (39): c++: Sort
