    gcov: Make gcov_seek() static
    
    This function is only used by gcov_write_length() in the gcov-io.cc file.
    
    gcc/
    
            * gcov-io.cc (gcov_seek): Make it static.
            * gcov-io.h (struct gcov_summary): Do not mention gcov_seek().
    
    libgcc/
    
            * libgcov.h (gcov_seek): Remove define and declaration.
