322 dnl the great gob of text. Thus it's not processed for possible expansion.

325 dnl Since Emacs can't find matching pairs of quotes, boundaries are

330 ### If you add support for a new configuration, add code to this
331 ### switch statement to recognize your configuration name and select
332 ### the appropriate operating system and machine description files.
334 ### You would hope that you could choose an m/*.h file pretty much
335 ### based on the machine portion of the configuration name, and an s-
336 ### file based on the operating system portion. However, it turns out
337 ### that each m/*.h file is pretty manufacturer-specific - for
338 ### example mips.h is MIPS
339 ### So we basically have to have a special case for each
340 ### configuration name.
342 ### As far as handling version numbers on operating systems is
343 ### concerned, make sure things will fail in a fixable way. If
344 ### /etc/MACHINES doesn't say anything about version numbers, be
345 ### prepared to handle anything reasonably. If version numbers
346 ### matter, be sure /etc/MACHINES says something about it.
348 ### Eric Raymond says we should accept strings like "sysvr4" to mean
349 ### "System V Release 4"; he writes, "The old convention encouraged
350 ### confusion between `system' and `release' levels'."
