* Internet Explorer was 'integrated' into the O/S with the release of Win98.

|
* 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.
