Thanks Terje,

In this case Synge's patch which was for release 1.30.0 needs to be 
modified to use bad_lexical_cast. Could someone apply the following 
patch to make lexical_cast work again?

diff -u -r1.13 lexical_cast.hpp
--- lexical_cast.hpp    11 Apr 2003 10:49:52 -0000      1.13
+++ lexical_cast.hpp    12 Apr 2003 05:45:30 -0000

          Target result;

          if(!(interpreter << arg && interpreter >> result))
-            throw_exception(detail::no_lexical_conversion<Target, 
Source>());
+            throw_exception(bad_lexical_cast(typeid(Target), 
typeid(Source)));
          return result;
      }
  }
