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