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