Are there really linkers that we care about that don't understand<br>

Therefore @file never made it to the linker. The darwin linker option for a file containing a list of files is -filelist <file>.</div><div><br></div><div>Is the motivation for this is that some OSs have a limit to the number/size of command line arguments?
