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