Re: pain to use _fseeki64(), giving link errors
just out of curiosity, how do I extract the dll version information without using windows explorer?

This is the prescribed method if your application is dependent on the
version of DLL. A new version of the DLL may break your application.
So using a newer version of a DLL for an application that ships with
an older version isn't a good thing. However, since the DLL actually
resides in the directory with the application it should be used
regardless of PATH as long as you don't delete the DLL. The DLL-hell
is the reason for the implementation of manifest files. You can also
create a directory foo.exe.local and store your DLL in that directory
that foo.exe depends on.
