One thing comes to my mind where this will be a problem: header files from our external libraries. BTW: Having a piece of code that doesn't compile without warnings on all platforms (unless you've triggered a real compiler bug) is often a good candidate for a code redesign - if the compiler doesn't like it most human developers will often also have problems to understand it ;-) But - these are really the exceptions and not the common thing. Most warnings can be fixed without problems. Some warnings will need special handling as there's no way to fix it (without making the code even uglier), it might be necessary to exclude code paths (#pragma) or even complete files from the general rule, as there's no realistic way to fix this in any other way. We might even need a configure option to disable the "warning as error" feature completely on platforms / compiler versions where this doesn't work. However, my goal would be to get a warning free build on the buildbot platforms, as that would be a big step into the right direction and that would make the situation much better even for the "unsupported platforms" ...
