@Jax: The extern "C" thing matters, very very much. If a header file doesn't have one, then (unless it's a C++-only header file), you would have to enclose your #include with it:

extern "C" {
#include 
// include other similarly non-compliant header files
}

Basically, anytime where a C++ program wants to link to C-based facilities, the extern "C" is vital. In practical terms, it means that the names used in external references will not be mangled, like normal C++ names would. Reference.
