Can you be more specific about the actual limitation?  Is it possible
that the limit is 126 characters, not 160?  I have never heard about
160-character limit.

The stock DOS and Windows shells have a 126-character limit on passing
commands line to and from DOS programs.  More accurately, the DOS
function which invokes programs supports 126-character command lines.
DJGPP programs work around this limitation by passing command lines
via a memory buffer.

As long as you use DJGPP programs to invoke other DJGPP programs, I
don't see how can you not get the long command lines that are a
standard DJGPP feature, unless you explicitly invoke COMMAND.COM.
