The Unisys machine mentioned in the top-rated answer still seems to be sold. <br></blockquote><div><br></div><div>Has anyone ever written a non-twos-complement C++ compiler for this machine?</div></div></div><div class="gmail_extra">
Has anyone ever written <b>any</b> non-twos-complement C++ implementation?</div><div class="gmail_extra">And... does anyone intend to write a non-twos-complement <b>C++17</b> implementation?<br></div><div class="gmail_extra">
<br></div><div class="gmail_extra">If the answer to these questions is "don't know", how do we find out? Strawman suggestion: remove non-twos-complement support from the standard and wait to see if anyone complains (with the intent that we would restore such support if there are actual complaints, not just hypothetical ones). The world would have nearly four years to notice and react. Thoughts?</div>
