Hi there,

In trying to use the tag extension schemes  in "./contrib/tags" I came across a not so obvious limitation in the lines

#define	FIELD_SETLONGS	3
#define	FIELD_LAST			(32*FIELD_SETLONGS-1)
u_long	td_fieldsset[FIELD_SETLONGS];

in tif_dir.h. 

Here FIELD_LAST  indicates the maximum number of tags you may define in libtiff. If, for instance, you want to read Exif files it seems you need to increase FIELD_SETLONGS to accomodate the large number of tags.
