For the erroneous program

	int main(argc) int argc = 0; { return 0; }

GCC 2.2.2 outputs the same diagnostic twice:

	t.c:1: parameter `argc' is initialized
	t.c:1: parameter `argc' is initialized

Here is a patch.

	* c-decl.c (grokdeclarator): Remove duplicate diagnostic for
	initialized parameters; start_decl already does this.
