* which are commonly required by Win32 programs. Originally distributed with
* Internet Explorer as a free download, it became a core part of Windows when
* Internet Explorer was 'integrated' into the O/S with the release of Win98.
*
* All functions exported by ordinal are undocumented by MS. The vast majority
* of these are wrappers for Unicode functions that may not exist on early 16
* bit platforms. The remainder perform various small tasks and presumably were
* added to facilitate code reuse amongst the MS developers.
