I've gone ahead and emailed Bart just for completeness, but a quick
search of the DOSEMU bugtracker found something (unrelated) that said
this:

"[DOSEMU-1.3.3] Failure of DJGPP port of GNU Sed - ID: 1429741" (hi,
Andris!)

https://sourceforge.net/tracker/index.php?func=detail&aid=1429741&group_id=49784&atid=457447

(2007-5-20, bartoldeman responded):

"It is indeed a problem in the FreeDOS kernel. What happens is that
SED tries to read from the NUL device in raw mode; that only works
correctly in cooked mode. It is fixed in the FreeDOS kernel CVS now."

So yeah, upgrading the /usr/lib/dosemu/drive_z/kernel.sys file to
latest 2040 version apparently "seems" to have fixed it to work
without needing a patch to configure. Just FYI in case anyone else
cares (doubt it).
