Re: [Boost-users] [filesystem] Can't create absolute paths from stringson windows

I read this in the boost docs:

Rationale: It is not considered an error for rhs to include a root-directory 
because m_name might be relative or empty, and thus it is valid for rhs to 
supply root-directory.  For example, on Windows, the following must succeed:

path p( "c:", native );
p /= "/foo";
assert( p.string() == "c:/foo" );

So I tried the code and the first line blew up:
boost::filesystem::path: invalid name "c:" in path: "c:"

Thanks
