* Use -Wno-tautological-constant-out-of-range-compare for Clang (these warnings come from the sanity checks in generated IfcXXX files).
* Remove unused variable and typedefs + suppress uint->bool conversion warnings (MSVC) + add note about Clang in README
* MSVC uint->bool convesion warning fixes when IFC4 is defined
* README.md: add note about Visual C++ Build Tools and Bash on Ubuntu on Windows. Enhance the Compiling on *nix instructions.
* Fix newline.
* README.md tweak
* CMakeLists.txt: remove CHECK_ADD_OCE_OCC_DEF INCLUDE() for good as these are not needed any more at all (OCE codebase also checked and no signs of these).
* Preliminary MSYS2 + MinGW build scripts and instructions.
* CMakeLists.txt: MinGW tweaks, enforce C++03, suppress warnings for now.
* Fix some GCC warnings.
* Fix unused parameter warnings coming from Ifc*.h.
* Fix warning regarding unreachable code (++jt) on MSVC.
* Add IfcParse_EXPORT for IfcInvalidTokenException
* Fix potentially uninitialized pointer variables.
* Note about OpenCASCADE cyclic dependencies fix.
* GCC warning fix: don't generate 'current_enum' variable that is only set and not used for anything ever
* Work around -Wmaybe-uninitialized warnings about boost::optional constructs. Also prevent passing of negative values for --bounds.
* Remove unused variable.
* CMakeLists.txt: ENABLE_BUILD_OPTIMIZATIONS for GCC (simply enforce -03)
* Make possible to invoke run-cmake.bat, build-ifcopenshell.cmd (now bat), install-ifcopenshell.cmd (now bat) directly from File Explorer or command prompt without VS env vars set, if BuildDepsCache file exists, by utilizing CMake's --build functionality. Do not delete CMakeCache.txt always now in order to keep the build options consistent.
* win/readme.md tweaks + make the line width smaller
* Windows batch files: use the last modified BuildDepsCache. Show an error if GEN_SHORTHAND does not exist.
