 164 ### You would hope that you could choose an m/*.h file pretty much
 165 ### based on the machine portion of the configuration name, and an s-
 166 ### file based on the operating system portion.  However, it turns out
 167 ### that each m/*.h file is pretty manufacturer-specific - for

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