You can create a pre-filter script to translate CRs to LFs. For example, if you can run a unix (e.g. bash) shell, something like the following will work:
tr '\r' '\n' < mailbox | mhonarc -- -
Change "mailbox" to the name of your Eudora mailbox file. If you have options you need to pass to mhonarc, put them between "mhonarc" and the "--". See <http://www.mhonarc.org/MHonArc/doc/faq/usage.html#stdin> for more information.
