Subject: Update a portability kludge to keep it in sync with changes in the code
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=2f87fed2479017589051a5a99277e4278f6372e3;p=oota-llvm.git

Update a portability kludge to keep it in sync with changes in the code
which uses it. This is not ideal, but it ought to at least restore the
behavior to what it was before.
