Not being privy to Apple's decision making process, I can only guess that it is in response to their new Swift programming language which they are pushing heavily on iOS (and soon Mac OS X), in which '+' is the string concatenation operator. For projects written in Swift and incorporating legacy or portable components in C, C++, or Objective-C, the warning may help programmer's avoid the pitfall of thinking that '+' is also concatenation in the C-based languages. > Can we have them fix their compiler instead? If the above supposition is correct, then it's likely that Apple considers this a feature, not a bug which needs to be fixed. >> Resolve this issue. >> >> Signed-off-by: Eric Sunshine <sunsh...@sunshineco.com> -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
