| Earlier we discussed the standard option <samp><span class="option">-b</span></samp> which chooses among |
| different installed compilers for completely different target |
| machines, such as VAX vs. 68000 vs. 80386. |
| |
| <p>In addition, each of these target machine types can have its own |
| special options, starting with ‘<samp><span class="samp">-m</span></samp>’, 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. |
| |
| <p>Some configurations of the compiler also support additional special |
| options, usually for compatibility with other compilers on the same |
| platform. |
