sure. OTOH, it's also a PITA to be able to maintain and enhance winedbg

We'll have to deal with (to name a few):
- dwarf debug symbols
- C++ ABI (if we want to provide a decent C++ environment for WineLib)
- portability to other processors

I'm not pushing for eliminating WineDbg, but adding with minor cost a
real
support for gdb in wine would be rather neat. Unfortunately, there's no
solution that'll meat all our expectations... but with two, we cover
quite
what we need
