Hey no problem, just add -Werror to your compiler flags (C/C++/Java) or '<TreatWarningsAsErrors>true</TreatWarningsAsErrors>' to your csproj (C#).
You will have a better, more reliable, and safer codebase once you clean up the legacy mess and turn this on..
Plus you get out of the habit of not reading output from the compiler because there are so many warnings...
