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

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