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