I think that GCC version should be the same, which was used to build the project: it can be higher or lower than 4.2.1

Yes, seems we can't get agreement here, so I am planning to abandon this.

Still we have no example when GCC x.y.z can compile something, but clang with -fgnuc-version=x.y.z can't process this project with some critical errors (but works ok with -fgnuc-version=4.2.1). But it's easy to create an example when -fgnuc-version=4.2.1 doesn't work (example in the description).
