128 ### If you add support for a new configuration, add code to this

132 ### You would hope that you could choose an m/*.h file pretty much
133 ### based on the machine portion of the configuration name, and an s-
134 ### file based on the operating system portion. However, it turns out
135 ### that each m/*.h file is pretty manufacturer-specific - for
136 ### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
137 ### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
138 ### machines. So we basically have to have a special case for each
139 ### configuration name.
141 ### As far as handling version numbers on operating systems is
142 ### concerned, make sure things will fail in a fixable way. If
143 ### /etc/MACHINES doesn't say anything about version numbers, be
144 ### prepared to handle anything reasonably. If version numbers
145 ### matter, be sure /etc/MACHINES says something about it.
147 ### Eric Raymond says we should accept strings like "sysvr4" to mean
148 ### "System V Release 4"; he writes, "The old convention encouraged
