### If you add support for a new configuration, add code to this
### switch statement to recognize your configuration name and select
### the appropriate operating system and machine description files.
### You would hope that you could choose an m/*.h file pretty much
### based on the machine portion of the configuration name, and an s-
### file based on the operating system portion. However, it turns out
### that each m/*.h file is pretty manufacturer-specific - for
### example mips.h is MIPS
### So we basically have to have a special case for each
### configuration name.
###
### As far as handling version numbers on operating systems is
### concerned, make sure things will fail in a fixable way. If
### /etc/MACHINES doesn't say anything about version numbers, be
### prepared to handle anything reasonably. If version numbers
### matter, be sure /etc/MACHINES says something about it.
###
### Eric Raymond says we should accept strings like "sysvr4" to mean
### "System V Release 4"; he writes, "The old convention encouraged
### confusion between `system' and `release' levels'."

### The two are the same except on a few systems, where they are made
