Original commit message from CVS: Patch by: Ole André Vadla Ravnås <ole.andre.ravnas@tandberg.com> * gst/gsttrace.c: * libs/gst/net/gstnetclientclock.c: (gst_net_client_clock_new): * libs/gst/net/gstnettimepacket.c: (gst_net_time_packet_send): * libs/gst/net/gstnettimeprovider.c: (gst_net_time_provider_new): Fix a couple of missing includes for MSVC2005 and a C99 issue. Also, starting with 2.14.0, GLib won't provide a pipe() macro any longer, so use _pipe() directly (#492077). * win32/common/dirent.c: (_treaddir): Add a couple of casts to make it build without warnings with MSVC. * win32/common/libgstreamer.def: Add some more symbols that need to be exported.
