Thanks.  The patch seems fine, but before you can commit it:

- Do you have an FSF copyright assignment?  For this patch it may
  not be needed, but you will need one before we can accept any
  more contributions from you.

- You need to add ChangeLog entries and format the code according
  to the guidelines in http://gcc.gnu.org/contribute.html.
