           Summary: Setting enum value to the last member of another enum
                    causes int overflow error

I encountered this when writing interfaces for a C library.

Code sample:

    enum A {
        start,
        end
    }

    enum B {
        start = A.end,
        end
    }

> rdmd -main ./test.d 
./test.d(9): Error: enum member test.B.end initialization with (B.start + 1)
causes overflow for type 'int'
Failed: ["dmd", "-main", "-v", "-o-", "./test.d", "-I."]
