Added a warning comment about curlbuild.h inclusion leading path.

 */

#include "curlver.h"         /* libcurl version defines   */

/* The leading path on the following include statement is required by the

   autobuild system (tests/testcurl.pl) because curlbuild.h is not generated

   in the same directory as curl.h in this special case. As long as the

   autobuild system works that way, do not remove it, unless you know what

   you're doing. */

#include "curl/curlbuild.h"  /* libcurl build definitions */

#include "curlrules.h"       /* libcurl rules enforcement */
