245 ### If you add support for a new configuration, add code to this
246 ### switch statement to recognize your configuration name and select
247 ### the appropriate operating system and machine description files.
249 ### You would hope that you could choose an m/*.h file pretty much
250 ### based on the machine portion of the configuration name, and an s-
251 ### file based on the operating system portion. However, it turns out
252 ### that each m/*.h file is pretty manufacturer-specific - for
253 ### example hp9000s300.h is a 68000 machine;
254 ### mips.h, pmax.h are all MIPS
255 ### machines. So we basically have to have a special case for each
256 ### configuration name.
258 ### As far as handling version numbers on operating systems is
259 ### concerned, make sure things will fail in a fixable way. If
260 ### /etc/MACHINES doesn't say anything about version numbers, be
261 ### prepared to handle anything reasonably. If version numbers
262 ### matter, be sure /etc/MACHINES says something about it.
264 ### Eric Raymond says we should accept strings like "sysvr4" to mean
265 ### "System V Release 4"; he writes, "The old convention encouraged
266 ### confusion between `system' and `release' levels'."
