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