Possibility to build OCCT using Visual Studio 2008 (VC9) is restored.
For that:
- template functions and classes from namespace std or tr1 (for VC9) are imported to namespace opencascade which is then used instead of std in relevant places
- templates not provided by compiler (VC9) but required for OCCT are defined in this namespace (in Standard_Handle.hxx)
- methods implementing move semantics are excluded for VC9 compiler (which does not support && syntax)
- support of vc9 compiler is restored in build procedures and environment scripts
- check of type of the current class in macros DEFINE_STANDARD_RTTI* is refactored
VS 2008 is restored in the list of supported platforms on Overview / System Requirements.
Macro defining Handle class is replaced by template class implementing the same concept (defined in Standard_Handle.hxx and Standard_Transient.hxx), opencascade::handle<>.
Header file Standard_DefineHandle.hxx becomes deprecated: the only useful macro DEFINE_STANDARD_RTTI is defined now in Standard_Type.hxx. Standard_DefineHandle.hxx is kept for compatibility, it defines macros previously used for definition of Handles and RTTI as empty. Macro DEFINE_STANDARD_HANDLE(C1,C2) is also kept for compatibility; now it expands to typedef "Handle_C1" to corresponding handle class.
Definitions of macro Handle() and STANDARD_TYPE() moved from Standard_Macro.hxx to Standard_Handle.hxx (new file) and Standard_Type.hxx, respectively.
New template class NCollection_Shared added, allowing to define sub-class manipulated by handle, for any non-transient class.
