139 ### If you add support for a new configuration, add code to this
140 ### switch statement to recognize your configuration name and select

143 ### You would hope that you could choose an m/*.h file pretty much
144 ### based on the machine portion of the configuration name, and an s-
145 ### file based on the operating system portion. However, it turns out
146 ### that each m/*.h file is pretty manufacturer-specific - for
147 ### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
148 ### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
149 ### machines. So we basically have to have a special case for each
150 ### configuration name.
152 ### As far as handling version numbers on operating systems is
153 ### concerned, make sure things will fail in a fixable way. If
154 ### /etc/MACHINES doesn't say anything about version numbers, be
155 ### prepared to handle anything reasonably. If version numbers
156 ### matter, be sure /etc/MACHINES says something about it.
