Fedora is improving cross compiling support and the very latest MinGW packages
(w64-based) are going into Fedora 17. I was interested in using gstreamer for
grabbing frames from a webcam and noticed that, by default, the ksvideosrc
(winks) plugin is not compiled. The winks Makefile has a specific comment that
the plugin is "not buildable", however, I have built it under MinGW with a few
minor changes.

The attached patches are broken into the following:
1-winks Makefile: Pretty self explanatory.
2-sys Makefile: Self explanatory, but you'll probably want a configure-tunable
switch for winks.
3-ksvideohelpers.c: MEDIASUBTYPE_I420 is already defined by MinGW-w64. This
should be tunable with a #if !define block.
4-kshelpers.c: STATIC_KSPROPSETID_Wave_Queued is not defined if NTDDI_VERSION
is greater than NTDDI_WS03 according to the MinGW-w64 header ksmedia.h. I just
defined it in the source as a workaround.

The resulting binary (libgstwinks.dll) reports the ksvideosrc video source when
I run gst-inspect in Windows 7. It shouldn't be too difficult to get this
plugin officially enabled with autotools should it?
