Detailed Description

By the moment, only operations necessary for reference counter in Standard_Transient objects are implemented.

Currently only two x86-based configurations (Windows NT with MS VC++ compiler and Linix with GCC) are really supported. Other configurations use non-atomic C equivalent.
