46 dnl Since XEmacs has configuration requirements that autoconf cannot
47 dnl meet, this file is an unholy marriage of custom-baked

1047 dnl You would hope that you could choose an m/*.h file pretty much
1048 dnl based on the machine portion of the configuration name, and an s-
1049 dnl file based on the operating system portion. However, it turns out
1050 dnl that each m/*.h file is pretty manufacturer-specific - for
1051 dnl example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
1052 dnl all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
1053 dnl machines. So we basically have to have a special case for each
1054 dnl configuration name.
1056 dnl As far as handling version numbers on operating systems is
1057 dnl concerned, make sure things will fail in a fixable way. If
1058 dnl /etc/MACHINES says nothing about version numbers, be
1059 dnl prepared to handle anything reasonably. If version numbers
