+/* The above workaround now causes more problems with the latest MS compiler.
+ * Visual Studio 2010's /GS option tries to guard against buffer overruns.
+ * /GS is on by default if you specify optimizations, which we do globally
+ * via /W3 /O2. However the above selective turning off of optimizations means
+ * that /GS issues a warning "4748". And since we treat warnings as errors (/WX)
+ * then the compilation fails. There are several possible solutions
+ * (1) Remove that pragma above as obsolete with VS2010 - requires testing.
+ * (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).
