OK, that part of the config.h.in file is copied directly from the
argument to the AH_BOTTOM macro in configure.in.  I didn't realize
that autoconf would do any processing of that text.  Would it work for
you if we rewrote that section as

  #if defined (__WIN32__) && ! defined (__CYGWIN__)
  #define OCTAVE_HAVE_WINDOWS_FILESYSTEM 1
  #elif defined (__CYGWIN__)
  #define OCTAVE_HAVE_WINDOWS_FILESYSTEM 1
  #define OCTAVE_HAVE_POSIX_FILESYSTEM 1
  #else
  #define OCTAVE_HAVE_POSIX_FILESYSTEM 1
  #endif
