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