I see.  So clang isn't really usable on Windows right now then?

I presume this is something the clang devs would like to address eventually?
A C++ compiler without exception handling is hardly a C++ compiler.

A slightly different question -- any idea how many developers are
actively working on clang and how many are actively working on the
core parts of LLVM that clang relies on?

My impression is that LLVM is a pretty big project with some nice
corporate backing.  But maybe the actual amount of activity is less
than I'm thinking...   I'm just surprised that something like
exception handling is working yet.  Or maybe it's just that none of
the devs or corporate backers are interested in Windows?
