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