I bootstrapped and tested Andriy's patch on amd64-unknown-freebsd8.1
without regressions:

  http://gcc.gnu.org/ml/gcc-testresults/2010-09/msg02492.html  (without)
  http://gcc.gnu.org/ml/gcc-testresults/2010-09/msg02490.html  (with)

(In fact, libgomp and libmudflap each lost warnings and failure,
respectively, but I believe that was timing issues.)


If approved, I can commit this to HEAD and the 4.5 branch.


For the record, below the original patch with a ChangeLog of mine.

Thanks.  Somehow this fell through the cracks, but I applied the
following change now.

Thanks, Andriy!  This patch will be in GCC 4.6.0 and I am also thinking
to apply it to the GCC 4.5 branch given that it brings this in line with
the system compiler.
