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