380 ### based on the machine portion of the configuration name, and an s-
381 ### file based on the operating system portion. However, it turns out
382 ### that each m/*.h file is pretty manufacturer-specific - for
383 ### example mips.h is MIPS
384 ### So we basically have to have a special case for each
385 ### configuration name.

388 ### concerned, make sure things will fail in a fixable way. If

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