 case cannot be implemented efficiently.
 
+We probably have to do something like this in the future.  The C++ header
+<limits> contains a lot of code like this:
+   static const int digits10 = __LDBL_DIG__;
+   static const int min_exponent = __LDBL_MIN_EXP__;
+   static const int min_exponent10 = __LDBL_MIN_10_EXP__;
+   static const float_denorm_style has_denorm
+     = bool(__LDBL_DENORM_MIN__) ? denorm_present : denorm_absent;
+ ... since this isn't being used in an #ifdef, it should be easy enough to taint
+the decl for these ivars.
