XCode new warnings

[dvkch]

Hi

This would be very nice to change the build warnings in the project and to display all the following mistakes :

• implicit signedness conversion
• implicit conversion between float, double and int
• etc

I had few issues with projects of mines where these conversions used to cause serious crashes (like uint set to -1...) and I am sure many of us set these warnings a long time ago.

Thanks ;-)
