197 ### based on the machine portion of the configuration name, and an s-
198 ### file based on the operating system portion. However, it turns out
199 ### that each m/*.h file is pretty manufacturer-specific - for
200 ### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
201 ### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
202 ### machines. So we basically have to have a special case for each
203 ### configuration name.
205 ### As far as handling version numbers on operating systems is
206 ### concerned, make sure things will fail in a fixable way. If
207 ### /etc/MACHINES doesn't say anything about version numbers, be

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