I don't work with clang internally so I do not know why this would be 
the case. Is this a current limitation of clang on all platforms, or 
just with MingW under Windows ?

Trying out clang with the Boost clang toolset, which is setup for Linux, 
I did not get the impression that the errors had anything to do with 
exception support. But I do not think the Boost Build clang toolset for 
Linux is setup correctly to work with MingW under Windows in the first 
place given that the errors were so immediate.

I truly think that a clang toolset for MingW on Windows needs to be 
created by a Boost Build developer based on the gcc MingW toolset, with 
whatever changes clang needs, but I know very little about doing this 
for Boost Build or about clang itself, so I hope someone else takes up 
the challenge. I know that Steve Watanable mentioned he might do it and 
I also got a response from Rene Rivera on the Boost Build mailing list. 
I would understand if it is not possible to get clang with MingW to work 
as a replacement for gcc with MingW, but I would still be curious to 
know why. I do realize that the goal of clang is to be ideally 100% 
conformant with the C++ standard whereas gcc may settle for less and a 
more practical implementation which lets it work with MingW under Windows.
