<br>
I have a couple of problems while trying to compile my program using Clang-cl. First issue, even passing /GR- and Xclang -fno-rtti I get:<br>

fatal error: too many errors emitted, stopping now [-ferror-limit=]<br>
2 warnings and 20 errors generated.<br>
<br>
And I can't find a switch for disabling exceptions.<br>
<br>
<br>
<br>
<br>
Second problem (I think I've encountered this before and fixed it with -fno-delayed-template-parsing, however it doesn't seem to work on clang-cl or the argument has since been removed from clang)<br>
