Yes. I finally committed the valid change to have it working on Windows 
both inside and outside GSTreamer (dllimport/dllexport using 
GST_EXPORT). And it works fine.

But now the buildbot complains about GST_CAT_DEFAULT when making the 
documentation :
http://build.fluendo.com:8080/FC1-gst/events/255/log

gtkdoc-mktmpl --module=gstreamer | tee tmpl-build.log
