The *C compiler* has no business installing files that belong to the *C library* (most likely GNU libc on a GNU/Linux host). The reason you're seeing the C++ headers is that the GCC tarball contains the C++ library. So really, when you install GCC, you're really installing a C *compiler* and a complete C++ *environment*. Hope that helps.
