[Ipopt] Compiling test programs in Visual Studio 2005

I wouldn't be so sure that this is from the intel side.
Checking a fairly old VS2003, __iob and __argv are defined in the libc 
derivates (libc, libcmt, libcd, ...), but in none of the Intel Fortran 
10 compiler libraries.
Maybe you can try to take libcmt or libc in again, or msvcrt.lib seem to 
define these too.

Hope this helps,
Stefan
