198	### You would hope that you could choose an m/*.h file pretty much
199	### based on the machine portion of the configuration name, and an s-
200	### file based on the operating system portion. However, it turns out
201	### that each m/*.h file is pretty manufacturer-specific - for
202	### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
203	### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
204	### machines. So we basically have to have a special case for each
205	### configuration name.
