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