368 ### If you add support for a new configuration, add code to this
369 ### switch statement to recognize your configuration name and select
370 ### the appropriate operating system and machine description files.
372 ### You would hope that you could choose an m/*.h file pretty much
373 ### based on the machine portion of the configuration name, and an s-
374 ### file based on the operating system portion. However, it turns out
375 ### that each m/*.h file is pretty manufacturer-specific - for
376 ### example mips.h is MIPS
377 ### So we basically have to have a special case for each
378 ### configuration name.
380 ### As far as handling version numbers on operating systems is
381 ### concerned, make sure things will fail in a fixable way. If
382 ### /etc/MACHINES doesn't say anything about version numbers, be
383 ### prepared to handle anything reasonably. If version numbers
384 ### matter, be sure /etc/MACHINES says something about it.
