261 dnl This used to use changequote, but, apart from `changequote is evil'
262 dnl per the autoconf manual, we can speed up autoconf somewhat by quoting
263 dnl the great gob of text. Thus it's not processed for possible expansion.
264 dnl Just make sure the brackets remain balanced.
266 dnl Since Emacs can't find matching pairs of quotes, boundaries are
267 dnl indicated by comments.
271 ### If you add support for a new configuration, add code to this
272 ### switch statement to recognize your configuration name and select
273 ### the appropriate operating system and machine description files.
275 ### You would hope that you could choose an m/*.h file pretty much
276 ### based on the machine portion of the configuration name, and an s-
277 ### file based on the operating system portion. However, it turns out
278 ### that each m/*.h file is pretty manufacturer-specific - for
279 ### example mips.h is MIPS
280 ### So we basically have to have a special case for each
281 ### configuration name.
283 ### As far as handling version numbers on operating systems is
284 ### concerned, make sure things will fail in a fixable way. If
285 ### /etc/MACHINES doesn't say anything about version numbers, be
286 ### prepared to handle anything reasonably. If version numbers
287 ### matter, be sure /etc/MACHINES says something about it.
289 ### Eric Raymond says we should accept strings like "sysvr4" to mean
290 ### "System V Release 4"; he writes, "The old convention encouraged
291 ### confusion between `system' and `release' levels'."
