Applying the attached patch should help.
Also, please consider switching the upstream source of this package to
<https://github.com/stsp/dosemu2>. It's theoretically still unstable,
but it's more actively maintained than the SourceForge repository, and
by the same person (to my knowledge). It has an analogous patch already
applied:
<https://github.com/stsp/dosemu2/commit/a5fb2f6f772af161b5cce24f77dc30b34aada082>.
