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