XEmacs 21.5 no-MULE "make check" failure

I took a quick look today at why XEmacs 21.5 no-MULE is failing "make check". I still don't know why, but I'm sending this message to record what I did, and also in the faint hope that somebody who knows something might see this message and have an "aha!" moment. I ran a MULE and a no-MULE XEmacs 21.5 side by side as they stepped through the failing case. Everything was identical up through the call to detect_coding_type (data->st, src, n); on line 3850 of file-coding.c. The next line is: data->actual = detected_coding_system (data->st); The MULE XEmacs got #<coding-system raw-text no-conversion>, but the no-MULE XEmacs got #<coding-system binary no-conversion eol-type=lf>. I have not yet tried stepping through detected_coding_system to see where the two went down different paths. -- Jerry James http://www.ittc.ku.edu/~james/
