              <LI><B>File Mappings:</B> Every file must be mapped so as to 
              identify it to the compiler. That is, this panel tells CodeWarrior 
              that files ending in .cpp are C++ source files and should 
              therefore be compiled using the C++ compiler. See Figure 2-9 for 
              more examples. </LI></UL>

                    the C/C++ compiler whether to provide warnings as your code 
                    is being compiled. Sometimes source code can contain 
                    elements that aren't quite correct but are not necessarily 
                    errors. These are called warnings. You can instruct the 
                    compiler to treat all warnings as errors so that you can 
                    quickly examine the questionable code in the editor.

                    program code. This panel lets you specify a header file that 
                    the resource compiler uses when generating these interface 
                    elements. </LI></UL>

                    from your C or C++ source code. The settings in this panel 
                    help the compiler to optimize your code. This item will be 
                    labeled differently on each CodeWarrior platform. Figure 
                    2-11 shows the x86 version. This is discussed more in Lesson 
                    3. </LI></UL>

                    <LI><B>Global Optimizations:</B> This has got to be one of 
                    the most exciting and useful panels in all of CodeWarrior 
                    (see Figure 2-12). This panel allows you to set the global 
                    optimization level of the compiler. This means that you can 
                    control how efficient and fast the compiler tries to make 
                    your source code. However, speed comes at a price. The 
                    smaller and faster the source code, the more difficult it is 
                    to debug, and the longer it takes to compile. Fortunately, 
                    the panel spells it all out for you so you can make that 
                    decision <I>every time you optimize!</I> If you want to, I 
                    mean. You will have a great deal of fun with this panel as 
                    you adjust the settings to suit your needs and your 
                    projects. </LI></UL>
