&gt; - What&#x27;s with the whole &quot;language&quot; and &quot;compiler&quot; distinctions no one cares about?<p>People care about distiguishing C89 and C99 from GCC and clang and their versions. If we don&#x27;t want to block the road to future compilers for the same language (and we had other compilers in the past, they just aren&#x27;t maintained anymore), we&#x27;d better be careful to distinguish them.<p>&gt; - Why is the first stable release of the compiler not optimized to the max?<p>Because it&#x27;s the <i>first</i> stable release, not the last. We expect to improve still.
