My bad.

A plain constant has type int. A constant with a single L at the end has type long and one with LL at the end has type long long. UL and ULL suffixes give unsigned long and unsigned long long. So and generated program to yield the values should yield both the integer value and the strong representation of the value and tndd the type should be inferred from that.<br><blockquote type="cite"><div dir="ltr"><div id="__MailbirdStyleContent" style="font-size: 10pt;font-family: Arial;color: #000000"><blockquote class="history_container" type="cite" style="border-left-style: solid;border-width: 1px;margin-top: 20px;margin-left: 0px;padding-left: 10px;min-width: 500px"><div style="font-family:Arial,Helvetica,sans-serif"><div id="__MailbirdStyleContent" style="font-size: 10pt;font-family: Arial;color: #000000"><div>Best,</div><div>Marcel</div></div></div></blockquote></div><span></span><br></div></blockquote></body></html>
