title: How do you remove command-line error: invalid macro definition: __STDCPP_DEFAULT_NEW_ALIGNMENT__=16 in Visual Studio Code (VSCode)
body: <p>When I create a new .h file in Visual Studio Code, I get red squiggles with the error message <code>command-line error: invalid macro definition: __STDCPP_DEFAULT_NEW_ALIGNMENT__=16</code>. I have not defined any custom macros. When I create a .cpp file this is not an issue, however if I change the file extension it becomes one. This error does not appear in a .cpp file, however it does apply if I create a .h file and change the file extension to .cpp. How can this be fixed?</p>
