What exactly did not work? Does 'diff3' give an error message that
it cannot find the file? Does a unit test from the diffutils package
not work? Does 'diff3' produce an output that is incompatible with
other tools (such as 'patch' or 'emacs')?

In other words, please state a "How to reproduce" recipe.

This #ifdef is true for mingw but false for native Windows executables
built with MSVC. Is that what you intended?

No tabs in gnulib source code, please. See gnulib/README for a way
to avoid tabs.
