OK, I added the ismac function but I just used the

  #if defined (__APPLE__) && defined (__MACH__)

directly in toplev.cc instead of using them to define MACOS since I
don't see that symbol being used in other places.

Also, I named the field "mac" instead of "macos", but if there are
good reasons to use "macos" instead, please explain.

Thanks,
