Ah, thank you. The missing (and undocumented) option. Is there any reason why -fglasgow-exts should be required? Judging by the flag reference material in section 4.17.15, -frules-off is used to turn RULES off explicitly, but there is no corresponding flag to turn them on - hence I assumed they would be enabled by default when -O or -O2 is set.
