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