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