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