It appears that GCC 1.35 is not properly skipping unnamed bitfields
when initializing a structure.  The following program:

	struct {
		int 	  : 8;
		int field : 8;
	} s = { 1 };

	main(){
		printf("s.field = %d\n", s.field);
		return 0;
	}

produces:

	s.field = 0

when it should produce:

	s.field = 1

The following patch should take care of it.
