/*
* Silly little bodge for getting GNU make to pass long commands
* to broken programs like the Microsoft and Watcom linkers. This
* tool is built with gcc, and invoked using GNU make. It echoes
* the arguments into a temporary file, and then passes that as a
* script to the utility in question. Ugly, but it does the job.
* An @ symbol marks that all commands from here on should go in
* the argument file, and a \ character indicates to convert slashes
* from / to \ format.
