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

1067 dnl based on the machine portion of the configuration name, and an s-
1068 dnl file based on the operating system portion. However, it turns out
1069 dnl that each m/*.h file is pretty manufacturer-specific - for

1071 dnl all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
1072 dnl machines. So we basically have to have a special case for each

1076 dnl concerned, make sure things will fail in a fixable way. If
