+operator new
+------------
+
+ This operator should take a type of size_t. But size_t has an unknown underlying
+ type. In the nuttx 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
