Go to New->Project->Select C in the New Project Dialog. In the right pane, the second option has a C++ icon beside it and the label is "%SimpletoCStdMakeConversionWizard.name%". I think the icon should be a "C" icon, and the label should be "Simple to C". Why is the label so complicated? The same goes for the 2nd and 3rd labels in the right pane if C++ is selected in the left pane. Also, the icon for the 2nd option here should show "C++" not "C".
This appears to be fixed with Andrew's latest import
The labels are changed but the icons are the same. Also if you notice now, the wizard name has changed so that under C++ projects, there are two wizards both called "Convert to C++" and there seems to be no indication which is the C to C++ and which is the Simple to C++ one. The one I know is supposed to be the C to C++ has a C icon beside it (maybe is supposed to be the indication) but the other one has a C++ icon, which doesn't indicate in any way that it converts from a simple to a C++ project. This is the same as Bug #25889 on eclipse.org.
It looks good now except the icon for Convert to C/C++ Project under the C projects list. It is a C++ icon. I'm not sure if this is how its meant to be, but if that is ok, then this bug is fixed.
The new project dialog is still confusing, but this specific problem has since been resolved. Closing.
