Deep EXPECT_EQ with double values

[andrea-cassioli-maersk]

I am writing some tests where I need to compare two struct that contains some nested double values, like in this simplified example

struct B {
 int x;
 double y;
};

struct A {
  B b;
};

Calling EXPECT_EQ sometimes fails for small numerical differences on the y member of B. In general I would use EXPECT_DOUBLE_EQ for comparison among double values, but here I cannot figure out what I should do (except of course compare all fields explicitly...).

Any suggestions?
