First, do not send diffs to generated files.  Always send diffs relative to the
source file (in this case configure.in).

Second, a ChangeLog entry just notes what changed, not why.  If the "why" is
complicated enough that you feel the need to explain it do so as comments
in the source.

ie:

        * configure.in (i[34567]86-*-sco3.2v4*): Target does not truncate
        filenames.
        * configure: Rebuilt.

I've fixed up your patch and installed.

Thanks,
