Build tools are updated to support building with Visual Studion 2019 toolset ClangCL (LLVM clang-cl): - In CMake builds, use of unsupported option "-std=c++0x" is avoided - Tool genconf recognizes availability of ClangCL toolset and proposes it in the list - Tool genproj recognizes new compiler specification VCVER=vclang and generates VS 2019 projects for it Note that vclang configuration puts binaries to folder "vc14" as it is compatible with vc14 CRT. Code is updated to build with Clang for Windows without errors and warnings: - In BVH classes, pure virtual destructors are replaced by empty ones, to avoid bogus compiler warning - In .lex files, pragmas are added to disable warnings in parser code - In OSD, signature of function _osd_wnt_set_error() is corrected to avoid warning on incorrect use of va_args (undefined behavior) - In OSD_Host, OSD_Parallel_TBB, warnings on usage of deprecated function are disabled - In Quantity_ColorRGBA and ViewerTest_CmdParser, incorrect use of predefined macro __FUNCTION__ assuming it was a string literal is avoided - In Standard_Macro.hxx, code is reordered to handle Clang for Windows appropriately - In AdvApp2Var_SysBase.hxx, inclusion of obsolete (MSVC-specific) header file is replaced by Standard_TypeDef.hxx - In Standard_ErrorHandler.hxx, empty statements added to avoid warning on unused class fields - In IVtkDraw and ViewerTest, interface is corrected to use actual type avoiding unnecessary type casts Off-topic: corrections of some errors (uninitialized class fields) reported by VS Code Analysis in TKernel
