Done.

It was working on the 4.6 branch from 4.6.0 to 4.6.2.

You probably won't need a separate testcase since the failure of the
sparc/sol2-unwind.h code manifests itself as lots testsuite failures in
ACATS, gnat.dg, and libjava.

The only report I know of is Eric's mail about the failure on s10_72, an
ancient Solaris 10 bi-weekly beta build, something almost nobody outside
Sun/Oracle will be able to test/verify since the corresponding ISO
images are no longer available.
