 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

 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

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