In addition, each of these target machine types can have its own special options, starting with ‘-m’, to choose among various hardware models, or configurations—for example, 68010 vs. 68020, floating coprocessor or none. A single installed version of the compiler can compile for any model or configuration, according to the options specified.

Some configurations of the compiler also support additional special options, usually for compatibility with other compilers on the same platform.
