* 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
* Windows/MSVC build scripts: option to build and use official Open CASCADE instead of the community edition.
* Fix C4800 warnings ("'Standard_Boolean': forcing value to bool 'true' or 'false' (performance warning)") + unnecessary integer cast.
* build-deps.cmd: fix OCCT download
* Fix MSVC linking against OCCT 7.0.0. Example executables fail still, needs research.
* occt-V7_0_0-9059ca1_CMakeLists.txt: add_definitions(-DHAVE_NO_DLL) in order to fix static linking to OCCT. Mark IfcOpenShell patches in the OCCT patch files for clarity.
* Patch OCCT in order to fix compliaction when HAVE_NO_DLL is defind. Clean up IfcOpenSHell's linker warnings by defining HAVE_NO_DLL.
* CMakeLists.txt: remove linking to the newly added OCCT libs, these are not needed when HAVE_NO_DLL is defined.
* cmake/CMakeLists.txt: make add_debug_variants() function to handle filenames/paths also. Apply the coding conventions while at it. Fixes#123.
* Patch OCCT's OpenGl_PrimitiveArray.cxx and XCAFDoc_GeomTolerance.cxx in order to fix Debug build. Do not trigger OCCT rebuild each time build-deps.cmd is ran.
* build-deps.cmd: fix OCCT file patch copy.
* Non-MSVC compiler: use -Wextra, suppress/fix -Wignored-qualifiers warnings.
* build-deps.cmd: do not check return values of copy commands as they seem not to be fully reliable.
* 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)
