61Each target machine types can have its own
62special options, starting with &lsquo;<samp><span class="samp">-m</span></samp>&rsquo;, to choose among various
63hardware models or configurations&mdash;for example, 68010 vs 68020,
64floating coprocessor or none.  A single installed version of the
65compiler can compile for any model or configuration, according to the
66options specified.
67
68 <p>Some configurations of the compiler also support additional special
69options, usually for compatibility with other compilers on the same
