* We use a "smart" matching algorithm that allows us to detect partial improvements
* in conformance. Specifically, two running indices are kept, one through the actual
* path and one through the expected path. The actual path index always increases,
* whereas, if the wine_entries_preceding field of the appropriate path_test_t element is
* non-zero, the expected path index does not increase for that many elements as long as
* there is no match. This allows us to todo_wine extra path elements that are present only
* in wine but not on native.
*
* Note that if expected_size is zero and the WINETEST_DEBUG environment variable is
* greater than 2, the trace() output is a C path_test_t array structure, useful for making
* new tests that use this function.
