making pointers to byte data be "guint8 *" rather than "char *",
and making buffers holding byte data arrays of "guint8" rather
than arrays of "char";
making pointers to text strings "char *" rather than "guchar *";
appropriately casting pointers (cast to "guint8 *" when passing
to routines expecting "guint8 *" or when assigning to "guint8
*");
making port-number preferences "guint";
making enum preferences "gint";
making hf_ variables "int".

is wrong; cast the "guint8" value to "guint" to widen it, so that adding
1 to it doesn't overflow. (But I don't think that cast should be
necessary - the "usual arithmetic conversions" in C should widen the
value anyway.)
