203### If you add support for a new configuration, add code to this

207### You would hope that you could choose an m/*.h file pretty much
208### based on the machine portion of the configuration name, and an s-
209### file based on the operating system portion. However, it turns out
210### that each m/*.h file is pretty manufacturer-specific - for
211### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
212### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
213### machines. So we basically have to have a special case for each
214### configuration name.
215###
216### As far as handling version numbers on operating systems is
217### concerned, make sure things will fail in a fixable way. If
218### /etc/MACHINES doesn't say anything about version numbers, be
219### prepared to handle anything reasonably. If version numbers
220### matter, be sure /etc/MACHINES says something about it.

222### Eric Raymond says we should accept strings like "sysvr4" to mean
223### "System V Release 4"; he writes, "The old convention encouraged
224### confusion between `system' and `release' levels'."
