I'm trying to write a program that involves downloading a file off the
internet if it can't find it locally. libcurl seemed to be easy enough
to use and good enough to do the job without a lot of work, however I
can't get my program to compile with the libcurl code added. Here is
the code:

#include <curl/curl.h>
...
CURL * easyhandle;
CURLcode success;
...
curl_global_init(CURL_GLOBAL_WIN32);
easyhandle = curl_easy_init();
curl_easy_setopt(easyhandle, CURLOPT_URL,
"http://www.stanford.edu/group/pandegroup/release/FAH4Console.exe");
curl_easy_setopt(easyhandle, CURLOPT_FILE, FAH_out);
curl_easy_perform(easyhandle);
curl_easy_cleanup(easyhandle);
curl_global_cleanup();

I get the following errors when I try to compile:
