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

1061 dnl based on the machine portion of the configuration name, and an s-
1062 dnl file based on the operating system portion. However, it turns out
1063 dnl that each m/*.h file is pretty manufacturer-specific - for

1066 dnl machines. So we basically have to have a special case for each
