From DJGPP info (Knowledge Base, Hidden Features, Features):
* Long command lines.
When DOS invokes programs, it limits the length of the command
line to 126 characters (excluding the program's name). This is a
ridiculously small limit; it doesn't even allow to compile GCC,
since many commands in GCC `Makefile's are much longer.
Therefore, DJGPP provides a mechanism to pass long command lines to
child programs. The actual command is stored in the transfer
buffer, and a pointer to that buffer is passed to the child
program instead of the command line itself. The startup code of
the child program then retrieves the actual command-line arguments
and puts them into the `argv[]' array passed to `main'.
DJGPP also supports the so-called "response file" method of
passing long command lines, whereby the command line is stored on
a disk file, and the name of that file is passed as
[EMAIL PROTECTED]'. For example:
ar cq libmylib.a @files-list
