You are mixing Microsoft new and old iostream libs.  MSVCRT.lib is
for new iostream and msvcirt.lib for old iostream. You
cannot do that.  Check http://msdn.microsoft.com and do a MSDN
search on MSVCRT.DLL, this will pull a Knowledge Base article
about new iostream and old iostream libs.

Also MSVCIRT.DLL and MSVCRT40.dll, both use M$ old isostream.
You cannot use msvcrt40.dll and msvcirt.dll for a same
executable.  Check msdn.microsoft.com for more details and how
to resolve conflicts.
