Hi, I ran into a problem when using the 2010 boost.process library 
within a Windows GUI application with WinMain() instead of main() 
without a console.

When I construct a context object the std[in|out|err]_behavior members 
are initialized in the constructor with calls to 
behavior::inherit::create(GetStdHandle(...)), which calls 
DuplicateHandle(). DuplicateHandle() fails with error 6 (invalid handle) 
since the application has no console and an exception is thrown.

So currently I don't see how I could use a context object from within a 
Windows GUI application since its constructor will always throw this 
exception.

What I want to do is start a child process and read its stdout as in the 
example "Communicating with child processes".

Best regards,
Wolfgang
