The files on the Wiki are out of date and don't work with current VC++,
for what it's worth I have a bunch of visualizers for VC12 sitting on my
hard drive that I've been meaning to do something with.

I'm ambivalent about whether these need to part of the official Boost
distribution - though I don't see why not.

Yes, but how are they installed into GDB?

Ah I see - you've updated the original visualizers - great!

I'll submit a few more then ;-)

My only (minor) quibble is that the project contains visualizers for
things not in Boost, but this is definitely a great idea.

Thanks for these, John.
