-operator new
-------------
-
-  This operator should take a type of size_t.  But size_t has an unknown underlying
-  type.  In the TinyAra sys/types.h header file, size_t is typed as uint32_t
-  (which is determined by architecture-specific logic).  But the C++
-  compiler may believe that size_t is of a different type resulting in
-  compilation errors in the operator.  Using the underlying integer type
-  instead of size_t seems to resolve the compilation issues. Need to
-  REVISIT this.
-
-  Once some C++ compilers, this will cause an error:
-
-    Problem:     "'operator new' takes size_t ('...') as first parameter"
-    Workaround:  Add -fpermissive to the compilation flags
