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