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

59 dnl - non-standard options

1060 dnl based on the machine portion of the configuration name, and an s-
1061 dnl file based on the operating system portion. However, it turns out

1064 dnl all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
1065 dnl machines. So we basically have to have a special case for each

1069 dnl concerned, make sure things will fail in a fixable way. If
