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

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

 230 ### matter, be sure /etc/MACHINES says something about it.
