+  \section ms_64bits Adds support for 64 bits integer
+    There has been many request to add support for 64 bits integer. Use case for this are:
+	- time is nowdays commonly represented with a 64 bits integer
+	- 64 bits integer are frequently used as primary key id in many systems
+	
+	Plans to add support is:
+	- must be optional, a configuration option since not all platforms provides 64 bits integer types.
+	- move definition of Int and UInt from forwards.h to config.h, with the required platform magic.
+	- C++ defines no standard to define 64 bits integer. Rely on msvc extension, and long long type that 
+	  is widely supported.
