Since also the gcov structures(gcov_info, gcov_fn_info, gcov_ctr_info) can change between gcc releases, as shown in gcc 4.7, they cannot be defined in a common header and need to be moved to a specific gcc implemention file. This also requires to make the gcov_info structure opaque for the common

The gcov in-memory format changed in gcc 4.7. The biggest change, which requires this special implementation, is that gcov_info no longer contains array of counters for each counter type for all functions and gcov_fn_info is not used for mapping of function's counters to these arrays(offset). Now
