cccl: A wrapper that calls visual c++ compiler.

One option to compile Open vSwitch code in windows
is to use Visual c++ compiler.

From http://cccl.sourceforge.net/ :
"cccl is a wrapper around Microsoft Visual C++'s cl.exe
and link.exe.  It converts Unix compiler parameters
into parameters understood by cl and link.  cccl's main
use is for using Unix build processes with Microsoft
compilers. Using cccl in conjunction with ports of Unix
utilities, it is possible to build many Unix packages
using MSVC, without modifying the build process."

There are couple of forks of the project in the internet.
