+ * (2) Stop treating warnings as errors - would be a backward step
+ * (3) Disable /GS - may help performance but you lose the security checks
+ * (4) Disable the warning with "#pragma warning( disable : 4748 )"
+ * (5) Disable planting the code with  __declspec(safebuffers)
+ * I've opted for (5) although we should investigate the local performance
+ * benefits of (1) and global performance benefit of (3).
