372 ### based on the machine portion of the configuration name, and an s-
373 ### file based on the operating system portion. However, it turns out
374 ### that each m/*.h file is pretty manufacturer-specific - for
375 ### example mips.h is MIPS
376 ### So we basically have to have a special case for each
377 ### configuration name.
379 ### As far as handling version numbers on operating systems is
380 ### concerned, make sure things will fail in a fixable way. If

383 ### matter, be sure /etc/MACHINES says something about it.
