+A new C preprocessor define NO_TAINT_SUPPORT was added that, if set, disables
+Perl's taint support altogether. Using the -T or -t command line flags will
+cause a fatal error. Beware that both core tests as well as many a CPAN
+distribution's tests will fail with this change. On the upside, it provides
+a small performance benefit due to reduced branching.
+Do not enable this unless you know exactly what you are getting yourself into.
