PATCH: fix PR 32948

[Ben Elliston <bje at au1 dot ibm dot com>]

This patch fixes PR other/32948, removing some warnings produced when
building GCC with the Intel compiler.  I produced this patch from
inspection of the compiler warnings reported by the submitter.  Tested
with a bootstrap on powerpc64-linux-gnu.

Okay for the trunk?

Thanks, Ben
