- * Definition of the _ARGS_ macro. The _ARGS_ macro such be used to
- * enclose the argument list of a function prototype. For example, the
- * function:
- * extern int main(argc, argv)
- * int args;
- * char **argv;
- *
- * Would have a prototype of:
- *
- * extern int main _ARGS_((int argc, char **argv))
- *
- * Currently the macro uses the arguments only when compiling the
- * KERNEL with a standard C compiler.
