--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
GCC uses consistent quotes, but depends on environment variables such as LANG.
Presumably one of the commands you are running sets LANG=C or similar, which
causes GCC to output ASCII apostrophes. If you want consistent results then set
LANG=C yourself before running any of the commands.
