/* The following line tells the configuration script what sort of
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 linux for Linux.
It isn't clear what to do on an SCO system.
- -machine=is386 is used for an Integrated Solutions 386 machine.
- It may also be correct for Microport systems.
-
-Cubix QBx/386 (-machine=intel386 -opsystem=usg5-3)
-
- Changes merged in 19.1. Systems before 2/A/0 may fail to compile etags.c
- due to a compiler bug.
-
-Prime EXL (-machine=intel386 -opsystem=usg5-3)
-
- Minor changes merged in 19.1.
