. major compat fixes for interoperation with wxw. . add crashlog_sender (modified version of debgrpt wxw sample). compiles but untested, will be changed heavily further improvements: . wposix no longer declares CRT functions. instead, use CRT headers.. but don't allow their (incorrect/non-POSIX) declarations to propagate to users. . split up win.cpp into wstartup, wutil, winit . extern "C" -> EXTERN_C . move sdl.* to lib/external_libraries and add png.h+zlib.h (fixes for and include of the library) This was SVN commit r5028.
