Details:

The signed types in the header are all defined without an explicit "signed".
This can result in annoying behavior if used in a bit-field. The signedness of
a plain "int" in a bit-field is implementation defined (in gcc controlled by
command line switches). But a (e.g.) int16_t should be always signed, even in
a bit-field, therefore an explicit "signed" is necessary.
