To be fair to them it's slightly worse than that.

There _is_ still a redistributable for C and we will continue to install it.  But it is all based on the non-redistributable
"Universal CRT" DLL.  They promise faithfully to never break it which you can test in the light of past history and Microsoft's
current insistence that a shorter release cycle trumps the need to test.

Of course they don't make the debug version available either thus knocking a hole in their remote debugging story.  So expect to see
debug versions of our DLLs fall off the installation as part of 3.0
