21 | /* The only 386 aout system we have here is GO32 from DJ. |
| 22 | These numbers make BFD work with that. If your aout 386 system | |
| 23 | doesn't work with these, we'll have to split them into different | |
| 24 | files. Send me (sac@cygnus.com) the runes to make it work on your | |
| 25 | system, and I'll stick it in for the next release. | |
