I'm planning to push the attached 1-liner bug fix to mainline tomorrow, when 
testing has completed.  I think this qualifies as "obvious".  There's no test 
case because I discovered it while testing the updated loop transformation 
patches, which are still a work in progress; it fixed an ICE in the newly-added 
tests for that.  This is clearly just a bug in existing code unrelated to the 
new functionality, though.

    OpenMP: GIMPLE_OMP_STRUCTURED_BLOCK bug fix
    
    This is a bug fix for commit a62c8324e7e31ae6614f549bdf9d8a653233f8fc,
    which added GIMPLE_OMP_STRUCTURED_BLOCK.  I found a big switch statement
    over gimple codes that needs to know about this new node, but didn't.

            * gimple.cc (gimple_copy): Add case GIMPLE_OMP_STRUCTURED_BLOCK.
