regenerated the makefiles. wxPostEvent() should work for wxGTK too (untested) 2. long -> wxCoord change for wxGTK and wxMSW, use wxUSE_COMPATIBLE_COORD_TYPES to get the old behaviour 3. wxHTML compilation fixes (for !wxUSE_HTML case) 4. a couple of handy macros in thread.h added git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@4054 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
