dnl based on the machine portion of the configuration name, and an s-
dnl file based on the operating system portion. However, it turns out
dnl that each m/*.h file is pretty manufacturer-specific - for
dnl example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
dnl all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
dnl machines. So we basically have to have a special case for each
dnl configuration name.
dnl As far as handling version numbers on operating systems is

dnl /etc/MACHINES says nothing about version numbers, be
dnl prepared to handle anything reasonably. If version numbers
dnl matter, be sure /etc/MACHINES says something about it.
