gotype successfully compiles the following program:

package a
var e,f = f^0i,0

while gccgo says:

go.go:2:12: error: incompatible types in binary expression

gccgo seems to be right, because 0i is imaginary literal.

Working as intended: 0i is an untyped complex constant that can be represented accurately as an int. Both go/types and gc agree with the spec. This is a gccgo bug.
