Nice! Thanks.

Here's a small patchlet to set the abi version to .18. With this,
check-abi will pass.

Benjamin, is this still uncommitted? I'm seeing abi_check failing...

Thanks,
Paolo.

Ok, now I see that the patch is in and a default configured build is 
fine abi-wise. Sorry about the false alarm.

If you are curious, the reason why I sent the message is that adding 
--enable-libstdcxx-time=rt (which should be more or less the default in 
the C++11 era) used not to lead to abi_check failures and it does now. 
Should look more into it...

Paolo.
