    Remove several warnings reported with W=1 · 609e053c

    Improved support for W=1 compilation flag by solving missing-prototypes
    and old-style-definition warnings.
    
    The libraries are compiling with warnings (which turn into errors with
    the Werror flag).
    
    Outside of libraries, some warnings cannot be fixed without heavy
    structural changes.
