Not really. I amused myself by converting it to plain C, building it and
running it against my localhost's Apache (which doesn't understand DAV at all)
and it did indeed get called properly:

< HTTP/1.1 501 Method Not Implemented
< Date: Wed, 21 Dec 2005 21:22:44 GMT
< Server: Apache/2.0.55 (Debian)

< Connection: close
< Content-Type: text/html; charset=iso-8859-1
*** write_data has been called: 293 bytes
* Closing connection #0

And for this, I used the program that now looks like this:

#include <curl/curl.h>

#include <stdlib.h>
#include <string.h>

size_t write_data(void *buffer, size_t size, size_t nmemb, void *userp)
{
   printf("*** write_data has been called: %d bytes\n", size*nmemb);
   return size*nmemb;
}

#define CHECKCC(x) \
    if ((cc = x) != CURLE_OK) { \
        printf("Failed at line %d with code %d\n", __LINE__, cc); \
        exit(1); \
    }

int main()
{
   CURLcode cc;
   const char *url = "http://localhost/";
   const char *userpwd = "aspen\\cucsvc:Bould3r";
   const char *method = "SEARCH";
   struct curl_slist *slist = NULL;
   slist = curl_slist_append(slist, "Accept: text/xml");
   slist = curl_slist_append(slist, "Depth: infinity");
   slist = curl_slist_append(slist, "Content-Type: text/xml");
   slist = curl_slist_append(slist, "Connection: Keep-Alive");

   const char *postdata =
     "<?xml version=\"1.0\"?><D:searchrequest xmlns:D=\"DAV:\" >"
     "<D:sql>SELECT \"http://schemas.microsoft.com/repl/contenttag\""
     " from SCOPE ('deep traversal of \"/exchange/adb/Calendar/\"') "
        "WHERE \"DAV:isfolder\" = True</D:sql></D:searchrequest>\r\n";

   CHECKCC(curl_global_init(CURL_GLOBAL_SSL))
     CURL *pcurl = curl_easy_init();
   CHECKCC(curl_easy_setopt(pcurl, CURLOPT_VERBOSE, 1))
     CHECKCC(curl_easy_setopt(pcurl, CURLOPT_URL, url))
     CHECKCC(curl_easy_setopt(pcurl, CURLOPT_CUSTOMREQUEST, method))
     CHECKCC(curl_easy_setopt(pcurl, CURLOPT_HTTPHEADER, slist))
     CHECKCC(curl_easy_setopt(pcurl, CURLOPT_POSTFIELDS, postdata))
     CHECKCC(curl_easy_setopt(pcurl, CURLOPT_POSTFIELDSIZE, strlen(postdata)))
     CHECKCC(curl_easy_setopt(pcurl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC))
     CHECKCC(curl_easy_setopt(pcurl, CURLOPT_USERPWD, userpwd))
     CHECKCC(curl_easy_setopt(pcurl, CURLOPT_WRITEFUNCTION, write_data))
     CHECKCC(curl_easy_perform(pcurl))
     curl_slist_free_all(slist);
}
