Eliminate old-style procedure declarators

Eliminate old-style procedure declarators

 * Old-style procedure declarators appeared as ...
	`myFunc (a, b, c)`
	`   int a, c; char * b;`
	`{}`
 * This style is very-very old C language.
 * In all modern C and C++, this procedure would be declared as ...
	`myFunc (int a, char * b, int c);`

 * Eliminate the awkward PARAMS() macro, which was used to simulate the
new style on old compilers that lacked the new style.

 * These patches only effect the DiffEngine
