wxTLS_PTR should have type of "T*" instead of being simply usable as "T*" because of its overloaded operator->(), otherwise the code relying on it being "T*" and compiling without problems in wxHAS_COMPILER_TLS case could fail to compile without compiler TLS support. Closes #13644. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@69832 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
