The HTArray_firstObject() macro is defined such that if you don't
use a variable named exactly "data" as the second parameter, you get
a syntax error (because of the reference to the "data" name in the
structure).

I suggest changing the variable in the define from "data" to "dp".
Here's a patch for the HTArray.html file:
