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

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