The assumption that SIZEOF_EVERYTHING_ELSE is defined when SIZEOF_INT is is wrong. While wxWidgets configure does define all SIZEOF_XXX at once, SIZEOF_INT could also be defined in some third party headers (e.g. Python.h) and we still need to define the other ones. In particular, doing this fixes the problem with SIZEOF_WCHAR_T not being defined during wxPython build. Closes #12013. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@64373 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
