State-Changed-Why:
    OK, I looked at build.log and I do see that gcc is reporting
    a reasonable thread model.  Can you verify that
    config/cpu/sparc/sparc32/bits/atomicity.h is being used
    to implement the spinlocks used by string<>?  This file
    was installed on your system in
    $prefix/include/g++-v3/<target-triple>/bits/atomicity.h .
    First of all, make sure the one installed is not the
    generic copy of atomicity.h (internally labelled:
    Generic version).  Thanks for your help.
