Intel compiler gives warnings if the static keyword is not at the beginning of the declaration and this happened when using it inside wxDEPRECATED() and related macros because the declaration started with __declspec(deprecated) or __attribute__((deprecated)) instead. To avoid this problem, simply move "static" outside the macro. Closes #12932. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@66966 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
