gccgo successfully compiles the following program: ``` go package e const c = 0>>"" ``` while gc says: ``` /tmp/test.go:2: cannot convert "" to type uint /tmp/test.go:2: invalid operation: 0 >> "" (shift count type string, must be unsigned integer) ``` gc seems to be right. gcc on rev 228818, gofrontend on a4bcd319d98ddc52b3e7d16ec87d92aad868ab05
