Ahh, sorry. I added the throw () to the constructor by mistake. The defined destructor is supplied otherwise the warnings in exceptions.warn are generated. The other option is to add "wlessrestrictedthrow" to the -erroff argument passed to the compiler. Supplying the destructor is slightly better in that it does not require modification to the command line used to compile any file using current_enable_exception.hpp directly or otherwise to get rid of the warnings.

Also, I removed several warning disablements from sun.jam as they were still missing the warnings on wave. The correct addition would be "uninitialized" as seen in the wave.warn file. However, this may be overkill as it is the only module that generates any warnings with the much shorter -erroff.
