157 ### You would hope that you could choose an m/*.h file pretty much
158 ### based on the machine portion of the configuration name, and an s-
159 ### file based on the operating system portion. However, it turns out
160 ### that each m/*.h file is pretty manufacturer-specific - for
161 ### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
162 ### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
163 ### machines. So we basically have to have a special case for each
164 ### configuration name.
166 ### As far as handling version numbers on operating systems is
167 ### concerned, make sure things will fail in a fixable way. If
168 ### /etc/MACHINES doesn't say anything about version numbers, be
169 ### prepared to handle anything reasonably. If version numbers
170 ### matter, be sure /etc/MACHINES says something about it.
172 ### Eric Raymond says we should accept strings like "sysvr4" to mean
