Hmm, strange. Right now, gcc+mingw5 setups still build after this patch 
for me at least.

The right place should be at the end, and I'm pretty sure it does that. 
You can have a look with e.g. "x86_64-w64-mingw32-gcc hello.c -o hello.exe 
-v", to print the actual link command invoked.

That said, libtool as used in vlc does some tricks where it parses the 
output from "$CC -v" and picks up the default libraries, and then links 
with -nostdlib, adding the default libs manually.

I don't insist on this fix though - I have a fix for mingw-w64 as well, 
that at least fixes my build failure - but I didn't really see why this 
would be necessary.
