When compiling code that is going to be used as a DSO, why is it important to use the -fpic/-fPIC flags? + + 2. On page 16, right hand column, there are two code samples. What is different about them? And why is the second one significant? + + 3. What is the easiest way to not export a variable or function? + + 4. Why did the author add "static" to last and next in the first code sample on page 18, left hand column? + + 5.
