    Re: Fix moxie libgloss issues with c99
    
    Two libgloss issues specific to moxie-elf that show up build with GCC trunk.
    
    First, putnum.c uses "print" without a prototype.  So I added one based on the
    function's definition in print.c.  Second sim-inbyte.c uses read, which comes
    from unistd.h, so this adds a suitable #include.
