Hi Vladimir,

Thanks for the fix. This fixes some of the regressions in the C-testsuite.

However I'm seeing similar fails in the fortran testsuite that I didn't include in the original bug report(sorry!). I've raised http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59959. It would be great if you could have a look.

Thanks,
Tejas.
