        * config/i386/i386.c (setup_incoming_varargs_ms_64): Set
        ix86_varargs_gpr_size and ix86_varargs_fpr_size to zero.

broke build for me, as it put statements before the declarations at the 
beginning of the function.  I'm checking this in to restore the build.

    	declarations to beginning of function.
