Add prefix INTERNAL_ to defined macro for internal header file. This change prevents an internal/foo.h from obscuring generic foo.h because former and later both guards from
#ifndef FOO_H #define FOO_H (...) #endif /FOO_H/
As internal/.h are included with #include <internal/.h>, INTERNAL_ looks a generic enough prefix.
