There is an important requirement for these custom definitions to work: cppcheck must properly treat abort() as a function which does not return. In order for that to happen, the __GNUC__ macro must be set to a high enough number (because system include directories are used and system headers compile attributes away if __GNUC__ is not high enough). __GNUC__ is thus set to the major version number of the GCC compiler used, which is what that latter does itself during compilation.
