201 dnl This used to use changequote, but, apart from `changequote is evil'
202 dnl per the autoconf manual, we can speed up autoconf somewhat by quoting
203 dnl the great gob of text. Thus it's not processed for possible expansion.
204 dnl Just make sure the brackets remain balanced.
206 dnl Since Emacs can't find matching pairs of quotes, boundaries are
207 dnl indicated by comments.
211 ### If you add support for a new configuration, add code to this
212 ### switch statement to recognize your configuration name and select
213 ### the appropriate operating system and machine description files.
215 ### You would hope that you could choose an m/*.h file pretty much
216 ### based on the machine portion of the configuration name, and an s-
217 ### file based on the operating system portion. However, it turns out
218 ### that each m/*.h file is pretty manufacturer-specific - for
219 ### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
220 ### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
221 ### machines. So we basically have to have a special case for each
222 ### configuration name.
224 ### As far as handling version numbers on operating systems is
225 ### concerned, make sure things will fail in a fixable way. If
226 ### /etc/MACHINES doesn't say anything about version numbers, be
227 ### prepared to handle anything reasonably. If version numbers
228 ### matter, be sure /etc/MACHINES says something about it.
230 ### Eric Raymond says we should accept strings like "sysvr4" to mean
231 ### "System V Release 4"; he writes, "The old convention encouraged
232 ### confusion between `system' and `release' levels'."
