 216 ### You would hope that you could choose an m/*.h file pretty much
 217 ### based on the machine portion of the configuration name, and an s-
 218 ### file based on the operating system portion.  However, it turns out
 219 ### that each m/*.h file is pretty manufacturer-specific - for
 220 ### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
 221 ### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
 222 ### machines.  So we basically have to have a special case for each
 223 ### configuration name.

 225 ### As far as handling version numbers on operating systems is
 226 ### concerned, make sure things will fail in a fixable way.  If

 228 ### prepared to handle anything reasonably.  If version numbers
 229 ### matter, be sure /etc/MACHINES says something about it.
