144 ### based on the machine portion of the configuration name, and an s-
145 ### file based on the operating system portion. However, it turns out
146 ### that each m/*.h file is pretty manufacturer-specific - for
147 ### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
148 ### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
