Subject: [PATCH] internal.h: make inline functions static

With some GCC configurations/build options it is possible for gcc to
ignore the inline hint. As the methods are not declared static, gcc
expects a definition to be provided elsewhere, which is not the case
here resulting in the following linker error:
