Sort of. :-) You still ignore the flag silently if it is not supported. 
I would prefer if a AC_MSG_WARN or AC_MSG_NOTICE in that case. If the 
user has explicitely given an argument, I think they deserves to know 
that is was to no effect. But then again, that's no regression so I 
accept if you will not fix it now.

Sounds good.
