1055 dnl based on the machine portion of the configuration name, and an s-
1056 dnl file based on the operating system portion. However, it turns out
1057 dnl that each m/*.h file is pretty manufacturer-specific - for
1058 dnl example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
1059 dnl all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
1060 dnl machines. So we basically have to have a special case for each
1061 dnl configuration name.
1063 dnl As far as handling version numbers on operating systems is
1064 dnl concerned, make sure things will fail in a fixable way. If
