</div>Yeesh, could you get any more condescending?</blockquote><div><br></div><div>I'm really sorry that came off as condescending, it wasn't meant to be. The cost imposed by switching to Clang's error messages was one we took very seriously. Working with GCC for a long time isn't a negative statement about the developer, it's a simple reality given the long history GCC has in the open source community as essentially the only compiler option available.</div>
<div><br></div><div>When evaluating Clang's error messages the threshold wasn't just being better based on the average feedback than GCC's messages; the improvement had to be sufficiently large to justify paying for the learning curve. There was a lot of debate, and a lot of things had to be fixed in Clang's diagnostics before it was clear that the cost/benefit tradeoff here supported transitioning to Clang's diagnostics across the board.</div>
