GNU compiler included with Mac OS X 10.2 (Jaguar) as well as August Developer Tools update contain a bug concerning #pragma interface handling that can only be worked around by not using them (and they are not necessary anyways) git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@16884 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
