Update config-default.h
We fixed PrivacyGuard build issues with gcc a while back, but the config wasn't updated then. Fixing it now.
#define HAVE_MAT_LOGGING
#define HAVE_MAT_STORAGE
#define HAVE_MAT_DEFAULT_HTTP_CLIENT
-#ifndef __GNUC__
-// PrivacyGuard is not presently compatible with gcc
#define HAVE_MAT_PRIVACYGUARD
-#endif
//#define HAVE_MAT_DEFAULT_FILTER
#if defined(_WIN32) && !defined(_WINRT_DLL)
#define HAVE_MAT_NETDETECT
