That's a gcc problem so it doesn't change for mingw-w64
Last time I tried to workaround it with libtool I had much pain because
libtool (by design) tries to outsmart us by changing the options we give
to the linker.
IMO we should:
* update the current hack for fedora
* use gcc built with --disable-shared for our releases / NB so people
using our libvlc.dll have no problem
