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