On the *printf problem, are you either able to identify which module it
dies in? or grab a stack trace?

The problem is usually down to a a conflict between vlc being written in
c99 and microsoft who write to god knows what. ie, a format specifier
that MS don't understand is used.

There is a further patch (yet to be written), that requires
mingw-runtime > 3.13 and deactivates the using of msvcrt _vsnprintf.

The problem is complicated by wince, which doesn't use the mingw-runtime
so needs some form of compatability.  One solution is to provide a
vsnprintf implementation for rubbish platforms, i got most of the way
there, but lost the will to live at implementing c99 compliant double
handling.
