And it's redundant as there is a wxDELETE() macro defined in wxWidgets
which you can safely put after an if() statement.  It is defined in
wx/defs.h along with a lot of other very handy definitions that hide
platform and compiler differences.  Many of them are not well documented
so you may need to grep the source code.
