fix the bug:
g_canon_name.c:125:5: warning: passing argument 2 of '__gss_copy_namebuf' from incompatible pointer type [enabled by default]

the 2nd argument of __gss_copy_namebuf should be address of *gss_buffer_t, \
but a *gss_buffer_t is assigned.

what __gss_copy_namebuf does is to alloc memory for a gss_buffer_desc and \
copy from src and return its address.

if following code failed, gss_release_name will free \
union_canon_name->external_name.value if it is not NULL.

OM_uint32 __gss_copy_namebuf(src, dest)
    gss_buffer_t   src;
    gss_buffer_t   *dest;

typedef struct gss_union_name_t {
	gss_mechanism		gss_mech;
	gss_OID			name_type;
	gss_buffer_desc		external_name;
	/*
	 * These last two fields are only filled in for mechanism
	 * names.
	 */
	gss_OID			mech_type;
	gss_name_t		mech_name;
} gss_union_name_desc, *gss_union_name_t;

typedef struct gss_buffer_desc_struct {
      size_t length;
      void FAR *value;
} gss_buffer_desc, FAR *gss_buffer_t;
