I got to the same point than you, now. I guess we have similar sources 
now, except that I modified GSTREAMER_EXPORT to define the variable that 
might be used out of libgstreamer. But the result is the same as yours 
(except that it's cleaner to submit a patch later).

Tomorrow (and the following WE) I'll compile GLib in debug mode and 
debug inside the code to see what's going wrong. Then it should be 
cleaner... If you want to compile GLib you just need to run "nmake -f 
makefile.msc" in their sources. I don't know yet and to have DEBUG 
defined when doing so but I will find out (or modify their makefile 
temporarily ;).
