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