 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

 223 ### configuration name.

 226 ### concerned, make sure things will fail in a fixable way.  If
