[lldb-dev] Running tests on windows?

Ahh actually you do have the compiler specified, and it is cl.exe. So yea,
this is definitely wrong and I think it actually the problem for two
reasons. The first reason is what I mentioned about the test suite not
working with cl.exe at all (because the Makefiles that build test programs
assume gcc-style command line options), and for a second reason because
there's a space in the path, and dosep doesn't support that (although it
could be made to). So if you fix the LLDB_TEST_COMPILER issue and set it
to clang, that should fix your problem.
