NOTE-START
-Intel 386 (-machine=intel386 or -machine=is386.h)
+Intel 386 (-machine=intel386)
The possibilities for -opsystem are: bsd4-2, usg5-2-2, usg5-3,
- isc2-2, 386-ix, esix, linux, sco3.2v4, and xenix.
+ isc2-2, 386-ix, and linux.
18.58 should support a wide variety of operating systems.
Use isc2-2 for Interactive 386/ix version 2.2.
Use 386ix for prior versions.
- Use esix for Esix.
Use linux for Linux.
It isn't clear what to do on an SCO system.
Minor changes merged in 19.1.
