  Applied with one slight alteration: I added a target selector to the .d file

#target: *-*-mingw32 *-*-cygwin *-*-pe

  I'm just verifying that it does indeed pass on a bunch of the small embedded
ARM/MCORE/WinCE PE targets, I'll fix any fallout but don't expect it.  (If
anyone wants, I could patch the BeOS target to do this warning as well.  I
think that's the only PE target that uses a different emulation.)

    cheers,
