355 ### You would hope that you could choose an m/*.h file pretty much
356 ### based on the machine portion of the configuration name, and an s-
357 ### file based on the operating system portion. However, it turns out
358 ### that each m/*.h file is pretty manufacturer-specific - for
359 ### example mips.h is MIPS
360 ### So we basically have to have a special case for each
361 ### configuration name.
363 ### As far as handling version numbers on operating systems is
364 ### concerned, make sure things will fail in a fixable way. If
365 ### /etc/MACHINES doesn't say anything about version numbers, be
366 ### prepared to handle anything reasonably. If version numbers
367 ### matter, be sure /etc/MACHINES says something about it.

370 ### "System V Release 4"; he writes, "The old convention encouraged
