As mentioned in the FAQ, there are currently 3 ways to pass long (more than
 127 chars) command lines from DJGPP programs (such as make, gcc) to other
programs: 
* the !proxy method, which is only suitable for calling another DJGPP
program
* the GNUish MSDOS method of passing arguments through environment
variables
* the response file method: passing arguments in @file

The MKS toolkit (a Korn shell + lots of Unix like utilities) can pass
arguments to the environment in a way similar to, but different from the
GNUish MSDOS method. Basically, the arguments are put at the start of the
environment, prepended with a ~ char. For instance, the command line:
	foo *.c "hello there"
would be passed through the environment as follows:
	~foo
	~file1.c
	~file2.c
	~hello there
	COMSPEC=c:/dos/command.com
	PATH=;/bin;/usr/bin

In addition, the abbreviated command line is still passed.

I am trying to make the toolkit work with DJGPP make. Unfortunately,
although I managed to get the parameters in the environment in this way, it
is not recognized by MKS programs. The documentation mentions something
about delimiting the command line with \r\n.

So I have 2 questions:

1. did anyone else manage to pass long command lines to MKS programs?

2. How can I get at the command line which is passed to a (non-DJGPP)
program?

I am using djgpp 1.12, make 3.71, gcc263.

Any help would be appreciated!
