[PD-dev] multiple def's in m_pd.h?

[James Tittle II]

hiya,

...is there a reason why there are multiple def's of t_inlet & t_outlet 
in m_pd.h?

...around 147:

EXTERN_STRUCT _outlet;
#define t_outlet struct _outlet

EXTERN_STRUCT _inlet;
#define t_inlet struct _inlet

...and around 341:

/* ----------------- patchable "objects" -------------- */
EXTERN_STRUCT _inlet;
#define t_inlet struct _inlet
EXTERN_STRUCT _outlet;
#define t_outlet struct _outlet

...?
