In Delphi 2009 whereabouts do you turn on the option to treat warnings as errors?
Just found the answer soon after I posted this! Might be useful for other people.
Navigate to 'Project -> Options - > Delphi Compiler -> Hints and Warnings
' and change the value of 'Output Warnings
' to 'as errors
'
I was looking for an option similar to what Visual Studio has
