[PD] PD-extended 0.40-3 : error when sending "blob" message to inlet

[Martin Peach]

Pd already has a t_int type declared in m_pd.h, the comments imply that it 
must be the same size as a pointer:

/* signed and unsigned integer types the size of a pointer:  */
#if !defined(PD_LONGINTTYPE)
#define PD_LONGINTTYPE long
#endif
#if !defined(PD_FLOATTYPE)
#define PD_FLOATTYPE float
#endif
typedef PD_LONGINTTYPE t_int;       /* pointer-size integer */
typedef PD_FLOATTYPE t_float;       /* a float type at most the same size */
typedef PD_FLOATTYPE t_floatarg;    /* float type for function calls */

So if Pd could handle int types just as it now handles float types, then you 
could pass pointers around (as well as unicode characters etc.). The blob 
code defines a type that consists of a pointer and a length, but that could 
be done further down the chain outside of core Pd if Pd could pass just the 
pointer around.
The t_int type is used internally but there is no integer atom.
