While DDT technically work oks with GDB (the GDB from mingw-w64 that 
is), you are right, there isn't a compiler on Windows that supplies 
debug info in the way GDB understands. See https://wiki.dlang.org/Debuggers.

DMD produces debug info COFF or OMF format, which GDB doesn't know 
anything about (nor ever will). LDC should in theory work with DWARF 
info, but this is broken somehow. Not because of LLVM though, since for 
example Rust on Windows works. As for GDC, it doesn't even supply 
binaries for Windows (that target Windows) -  it is not a supported 
platform.

BTW, Eclipse/DDT should in theory work with mago-mi as well, at least if 
the protocol is implemented correctly. Have you tried it? I dunno how 
complete your MI implementation is.
