This is commit e093a3b1b402c067254558d24ef2d7f39f552251 from the wx3.0
stable branch.
The correct error code and message is now output when an error takes
place. Previously it would report an error code of 0 and inform us that
"The operation completed successfully".
There was a version check in the menu handling, but Windows 8.1 and
Windows 10 weren't recognised and some pre Windows 98 code was used.
This is a combination of the following wxWidgets upstream commits.
