first source file

Compiling the attached sources:

  clang++ *.cpp

results in linking error, multiple definition of `__clang_call_terminate'.

This is probably the result of COFF not supporting the Linkage/Visibility
getClangCallTerminateFn uses:

    // Allow this function to be shared across translation units, but
    // we don't want it to turn into an exported symbol.

As a fix maybe another Linkage/Visibility combination will work or we could
turn off useClangCallTerminate() for mingw/coff targets.
