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