canonicalize_file_name simplification?

John,

In liboctave/file-ops.cc there is a 4-way #ifdef test to determine whether
there is some sort of function we can use for canonicalize_file_name.  The
end result is that I am seeing very different behavior between Linux and
__WIN32__ platforms.  Given that we have adopted gnulib and are using the
canonicalize module, can't we just call gnulib::canonicalize_file_name and
let it sort out which function to call?
