Mike,

The check here is legitimate, and if you remove it, you'll likely get a crash as few lines 
because of the cast :
    tSHP->tileshpfile = (shapefileObj *) tlp->layerinfo; /* shapefiles use layerinfo to point to a 
shapefileObj */

But you can accomplish what you want by adding a CONNECTIONTYPE OGR item in your 
layer definition. This will go through the OGR code path which also supports tile indexes ... 
provided they are OGR datasources themselves.
