Follow-up Comment #4:

After that change, cross-building for Windows with MXE Octave fails with the
following error:

src/x86_64-w64-mingw32-mkoctfile.cc: In function ‘int
octave_mkostemps_wrapper(char*, int)’:

Gnulib's fcntl.h defines O_BINARY for that platform. [1]
Do we want to include gnulib headers when building mkoctfile?  I don't know
the background for not using our wrappers when cross-compiling.
