 191 ### You would hope that you could choose an m/*.h file pretty much
 192 ### based on the machine portion of the configuration name, and an s-
 193 ### file based on the operating system portion.  However, it turns out
 194 ### that each m/*.h file is pretty manufacturer-specific - for
 195 ### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
 196 ### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
 197 ### machines.  So we basically have to have a special case for each
 198 ### configuration name.

 200 ### As far as handling version numbers on operating systems is
 201 ### concerned, make sure things will fail in a fixable way.  If
 202 ### /etc/MACHINES doesn't say anything about version numbers, be
 203 ### prepared to handle anything reasonably.  If version numbers
 204 ### matter, be sure /etc/MACHINES says something about it.
