250 dnl Just make sure the brackets remain balanced.
252 dnl Since Emacs can't find matching pairs of quotes, boundaries are
253 dnl indicated by comments.
257 ### If you add support for a new configuration, add code to this
258 ### switch statement to recognize your configuration name and select
259 ### the appropriate operating system and machine description files.
261 ### You would hope that you could choose an m/*.h file pretty much
262 ### based on the machine portion of the configuration name, and an s-
263 ### file based on the operating system portion. However, it turns out
264 ### that each m/*.h file is pretty manufacturer-specific - for
265 ### example hp9000s300.h is a 68000 machine;
266 ### mips.h, pmax.h are all MIPS
267 ### machines. So we basically have to have a special case for each
268 ### configuration name.
270 ### As far as handling version numbers on operating systems is
271 ### concerned, make sure things will fail in a fixable way. If
272 ### /etc/MACHINES doesn't say anything about version numbers, be
273 ### prepared to handle anything reasonably. If version numbers
274 ### matter, be sure /etc/MACHINES says something about it.
276 ### Eric Raymond says we should accept strings like "sysvr4" to mean
277 ### "System V Release 4"; he writes, "The old convention encouraged
278 ### confusion between `system' and `release' levels'."
