That's not the only work-around.  You can also use the response file
method for invoking a DJGPP program from a non-DJGPP one.

The current development sources of the DJGPP library include code
which allows to pass command lines up to 1KB from non-DJGPP to DJGPP
programs and vice versa, using the CMDLINE environment variable.  The
next DJGPP release will support this.

Note that passing long command lines from COMMAND.COM's prompt
requires some non-defualt setup of COMMAND.COM as well.
