This is a binary which opens the native file dialog.
As long as WCHAR, DWORD, BOOL keep the same size in 32 & 64 bit,
this binary works for both architectures.
Before this binary, the source was included in WinWorkstation.st
But sadly the file dialog did change the current directory.
To avoid this, we call the file dialog via a separate process (this binary).

The communication between stx and this binary works via shared memory and some SendMessage calls.
The binary is also checked in into the repository and it will not automatically compile as prereq of libview (until now).

There is no reason why it should not compile as prereq,
beside I dont have time (and missing knowledge) to integrate it.
But if you like, you have the cpp file, 
integrate it as prereq of libview (in windows case)
and create the makefiles.
