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

 133 ### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
