Thanks very much @bruno and sorry for the trouble here!  Looks like I was expecting a forward slash at the beginning, forgetting about drive letters on Windows -- and backslashes (actually looks like backslashes and forward slashes can get mixed?).

Indeed the output on windows looked like:

  #__include_macros "C:\b\slave\clang-x86-windows-msvc2015\clang-x86-windows-msvc2015\llvm\tools\clang\test\Preprocessor/dump_include.h" /* clang -E -dI */

which actually looks correct.  I'll have to correct my test here for this case.  Will have this updated in a couple of minutes.  Thanks very much!
