           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P

C:\src\llvm-mono>cl /c test.cc /nologo
test.cc(6): warning C4530: C++ exception handler used, but unwind semantics are
not enabled. Specify /EHsc

C:\src\llvm-mono>out\gn\bin\clang-cl /c test.cc
test.cc(6,3):  error: cannot use 'try' with exceptions disabled
  try {

For regular clang, exceptions are enabled by default so it's not an issue
there. But clang-cl should mention "/EHsc" in its diag, probably?
