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