[ros-dev] [ros-diffs] [jgardou] 64121: [KDGDB] - introduce KDGDB, a KDCOM-like DLL, wrapping the KD protocol and the GDB remote protocol together. It is not fully functional, but for now it permits source-level debuggin...

[Jérôme Gardou]

I thought about that, but considering the fact that using windbg for a 
GCC compiled OS or GDB for a MSVC compiled OS makes little sense 
(although one could use that for mixed kernel+drivers setup), I decided 
to go the KDCOM way.

I am open to good arguments for doing that another way though.
