I get the following warning:
c:\Boost Releases\boost\boost\lexical_cast.hpp(47) : warning C4224: nonstandard extension used : formal parameter 'arg' was previously defined as a type

I believe this is a new warning, I'm pretty sure I had an error/warning free program late last week.

The only "type" I can find which may be referred to is in boost/bind/arg.hpp
which is referenced from boost/bind.hpp

Is there some name collision that needs to be looked into between bind and lexical_cast ??

I'm _not_ representing that VC++ is accurately reporting that this is a non-standard extension (I really don't know), but thought a heads up might be in order.
