 | >Description:
 | When doing a 'file' on a sun3 dynamically linked executable, both SunOS NetBSD report the same thing: mc68020 demand paged dynamically linked executable not stripped.
 | But when doing a 'file' on a sun3 statically linked executable, NetBSD does not document that the file is 'executable'.  NetBSD shows: mc68020 demand paged not stripped, while SunOS shows: mc68020 demand paged executable not stripped".  Although its a pretty good hint that the file is an exectuble, being that NetBSD shows "mc68020", I believe that the magic file could be improved by having it say "mc68020 executable" or such for statically linked executables.
 | >How-To-Repeat:
 | Create statically linked executable under Sun3 SunOS 4.1.1, then copy to any NetBSD system.
 | >Fix:
 | Update the magic file to change "mc68020" to "mc68020 executable" and change "dynamically linked executable" to "dynamically linked".
 
 Here's a patch:
