Done.  A full cycle of bootstraps (32-bit/64-bit, Solaris 2.5.1, 2.6, 7, 8 
and 9, Java, Ada) has successfully completed on mainline, 3.4 branch and 3.3 
branch with your patch (and some others on mainline and 3.4 branch).

Needless to say this doesn't change my position :-)

Could that be the same problem as PR target/15253?
