I find it really odd that a WMS server would cehck the user agents 
before responding to client requests, but anyway, there is apparently a 
way to control the user agent value with Libcurl.  If you can build from 
source, then you could add the following line to maphttp.c around line 
339, just after the line that sets CURLOPT_URL:

   curl_easy_setopt(http_handle, CURLOPT_USERAGENT, "whatever you want");
