+Work around a C++11 incompatibility when compiling the gperf-generated

+  default/src/gx_head/engine/jsonrpc_methods.cc:211:26: error: reference to ‘hash’ is ambiguous
+	 register int key = hash (str, len);
+			    ^
+The solution is to run 'gperf -L C++' so that it generates code with
+appropriate C++ name-spacing to avoid the ambiguity.
