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

1062 dnl based on the machine portion of the configuration name, and an s-
1063 dnl file based on the operating system portion. However, it turns out

1067 dnl machines. So we basically have to have a special case for each
