Sounds like we ought to be able to just rely on compiler support once we drop support for GCC < 4.4 (probably after the Firefox 17 uplift). > Compilers that support scoped enumerations include gcc 4.4 and up, Clang 2.9 > and up, and VC++ 2011 and later.

Did you mean VC++ 2010 or 2012? There's no version called 2011. (VC 2010 is VC 10.0, and VC 2012 is VC 11.0, confusingly.) -Ted _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
