I don't have access to a windows machine so I can't debug this myself,
but I would suggest stepping through the execution of the
`org-babel-C-execute' function using edebug. This is done by first
placing the cursor inside the `org-babel-C-execute' function, evaluating
the function with C-u C-M-x, then executing a C code block. This should
give you some idea of what is going wrong where.
