Actually, your example program had several errors and I did point out the
most obvious one. You did (still do?) use CURLOPT_FILE without specifying the
CURLOPT_WRITEFUNCTION. That is not "legal" on windows.

Two other problems:

This didn't specify the third argument, TRUE or FALSE must be added.

This is a serious error, it should provide a pointer to a buffer as a third
argument. The buffer must be at least CURL_ERROR_SIZE bytes big.

> curlRes = curl_easy_setopt(curl, CURLOPT_MUTE, 1);

Obsolete. The MUTE option doesn't do anything in 7.8 and later.

Well, using proxy or not of course make libcurl work slightly different
internally, but both with and without is of course supposed to work
