So let me get this straight: not only do we now implicitly want to bump the required C compiler to C99 without any grace period worth mentioning [*1*], we are also all of a sudden no longer worried about a double digit percentage drop of speed [*2*]? Puzzled, Johannes Footnote *1*: I know, it is easy to forget that some developers cannot choose their tools, or even their hardware. In the past, we seemed to take appropriate care, though. Footnote *2*: With real-world repositories of notable size, that performance regression hurts. A lot. We just spent time to get the speed of SHA-1 down by a couple percent and it was a noticeable improvement here.
