Don't support this compiler any more, this allows to get rid of tons of MSVC6-specific workarounds, in particular we can now use Bind() and natural template functions calls in the library code. Also remove MSVC6 project and solution files and don't generate them when bakefile_gen is ran any more (removing the remaining occurrences of msvc6prj from the bakefiles results in weird bake-time errors, so it's simpler to just leave them there). git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76532 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
