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