Follow-up Comment #42:

Attached is a patch in which I got rid of the pragma conditionals in the
header files. I also added wrappers so that these conditionals are no longer
needed in load-save.cc and the parser.

The conversion between byte strings (UTF-8, what Octave uses) and wstrings
(UTF-16, what the Windows filesystem uses) is done in u8_to_wstring and
wstring_to_u8 which converts between std::string and std::wstring with the
respective encodings.

However, it now only compiles with gcc 5 or newer because it uses the C++11
function std::wstring_convert. I tried with gcc 5.4.0 in mxe-octave, and it
works as expected for me on Windows 10.

I am still not sure which conditionals should be used. I stuck with
OCTAVE_USE_WINDOWS_API. But I have also seen OCTAVE_HAVE_WINDOWS_FILESYSTEM
and ! OCTAVE_HAVE_POSIX_FILESYSTEM in other places. I do not know the build
system well enough to judge which should be used here...
