Ok. A fellow named Sebastian who says he works on the clang C++ also
said that it didn't support exceptions in C++. And also that the
current C++ support in clang is basically unusable.
But anyway, they're going to want exception support sooner or later,
too. Maybe there's some way for LDC and clang guys to collaborate or
divide up the work getting Windows exceptions into LDC? Or at least
work together to get LLVM guys to implement it?
