Yes, but it is not a big problem.
You can use the /k option of
command.com in a SHELL= line of
a config.sys, to make it call the
alternative autoexec.bat.
Example:
SHELL=C:\COMMAND.COM c:\command.com /E:2048 /k autoxxx.bat
and it will use autoxxx.bat instead
of autoexec.bat.
Coupled with $_emusys, which still
works, you can retain all the former
functionality.

You can just ignore that message
(the consequences are that dosemu
may work slower as it will use the
file instead of IPC), or you can
upgrade your dosemu further (to
1.3.1 or CVS), where this error no
longer exist.

Yes, upgrading from 1.0.x have a
few rough edges as a lot of the
code was rewritten and some things
now work differently.
