I grabbed the hourly tarball snapshot of the cvs tree 
dated 03-10-09-0400.

Do you plan to continue to support configurations/platforms lacking 
exceptions (through boost::throw_exception)?

If so, what would the replacement to this be:
#ifdef BOOST_REGEX_NON_RECURSIVE
   }
   catch(...)
   {
      // unwind all pushed states, apart from anything else this
      // ensures that all the states are correctly destructed
      // not just the memory freed.
      while(unwind(true)){}
      throw;
   }
#endif

Angus
