185 dnl per the autoconf manual, we can speed up autoconf somewhat by quoting

190 dnl indicated by comments.
194 ### If you add support for a new configuration, add code to this
195 ### switch statement to recognize your configuration name and select
196 ### the appropriate operating system and machine description files.
198 ### You would hope that you could choose an m/*.h file pretty much
199 ### based on the machine portion of the configuration name, and an s-
200 ### file based on the operating system portion. However, it turns out
201 ### that each m/*.h file is pretty manufacturer-specific - for
202 ### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
203 ### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
204 ### machines. So we basically have to have a special case for each
205 ### configuration name.
207 ### As far as handling version numbers on operating systems is
208 ### concerned, make sure things will fail in a fixable way. If
209 ### /etc/MACHINES doesn't say anything about version numbers, be
210 ### prepared to handle anything reasonably. If version numbers
211 ### matter, be sure /etc/MACHINES says something about it.
213 ### Eric Raymond says we should accept strings like "sysvr4" to mean
214 ### "System V Release 4"; he writes, "The old convention encouraged
215 ### confusion between `system' and `release' levels'."
