 210 ### If you add support for a new configuration, add code to this
 211 ### switch statement to recognize your configuration name and select
 212 ### the appropriate operating system and machine description files.
 213
 214 ### You would hope that you could choose an m/*.h file pretty much
 215 ### based on the machine portion of the configuration name, and an s-
 216 ### file based on the operating system portion.  However, it turns out
 217 ### that each m/*.h file is pretty manufacturer-specific - for
 218 ### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
 219 ### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
 220 ### machines.  So we basically have to have a special case for each
 221 ### configuration name.
 222 ###
 223 ### As far as handling version numbers on operating systems is
 224 ### concerned, make sure things will fail in a fixable way.  If
 225 ### /etc/MACHINES doesn't say anything about version numbers, be
 226 ### prepared to handle anything reasonably.  If version numbers
 227 ### matter, be sure /etc/MACHINES says something about it.

 229 ### Eric Raymond says we should accept strings like "sysvr4" to mean
 230 ### "System V Release 4"; he writes, "The old convention encouraged
