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