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