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