Ugh. Yeah, the Unix platforms are covered but not when building with
VC++. Not sure what to do about that. We'll have to sort this out when
the UIUC crew comes back from vacation/holidays. Until then, please
don't distribute any LLVM's built with VC++ unless you also comply with
the LGPL.

I've been thinking about converting our makefiles so that they could run
with the VC++ toolset. It would then be possible to create VC++
compatible DLLs and executables but via cygwin/make running to build it.
Not sure if that's a reasonable thing nor if we could still use libtool
in such a scenario.
