46 * Internet Explorer as a free download, it became a core part of Windows when
47 * Internet Explorer was 'integrated' into the O/S with the release of Win98.

50 * of these are wrappers for Unicode functions that may not exist on early 16
51 * bit platforms. The remainder perform various small tasks and presumably were
52 * added to facilitate code reuse amongst the MS developers.
