 it ``GCC'' no matter what the language context; however, the term

+Similarly, when we talk about Ada compilation, we usually call the

 We use the name ``GCC'' to refer to the compilation system as a
 whole, and more specifically to the language-independent part of the
 compiler.  For example, we refer to the optimization options as
 affecting the behavior of ``GCC'' or sometimes just ``the compiler''.
