I was chatting on #gdb earlier today and it sounds like getting a patch for the d programming language into gdb shouldn't be too bad. There's a patches mailing list and some kind of paperwork to resolve copyright issues.
Is there any legal/copyright issues that prevent the gdb patch from making it into gdb? Maybe demangling uses digital mars code? I'd really love to see complete support for D in gdb. It's really frustrating to not have it :(
