/*
* 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.
