You need some additional include paths.
Example:

-I "C:\Program Files\Analog Devices\VisualDSP 4.0
\Blackfin\contrib\ports\YOUR_CPU\include"
-I "C:\Program Files\Analog Devices\VisualDSP 4.0
\Blackfin\contrib\ports\YOUR_CPU\include\netif"
-I "C:\Program Files\Analog Devices\VisualDSP 4.0
\Blackfin\lwip\src\include"
-I "C:\Program Files\Analog Devices\VisualDSP 4.0
\Blackfin\lwip\src\include\lwip"
-I "C:\Program Files\Analog Devices\VisualDSP 4.0
\Blackfin\lwip\src\include\ipv4"
-I "C:\Program Files\Analog Devices\VisualDSP 4.0
\Blackfin\lwip\src\include\netif"

Maybe you want to use relative paths instead, that saves you the hassle of
updating paths
when migrating to a newer version for Visual DSP.
